2. INSTALLATION:

The system can be installed in several fashions in different platforms. There are even expert installations for High Performance Computing (HPC) for advanced and expert users. 
For novice users it is recommended that you use Windows since it is the simplest to install and the Graphic User Interface (GUI) was tested there. For HPC features you will need to use a Linux installation.

Simple Installation Instructions:
1. Download and Install Anaconda with python 2.7 version from  https://www.anaconda.com/download/
2. Install MIST into your anaconda directory by typing the following text in a command terminal: conda install mist -c jacob-barhak 
This installation should work on Windows and on Ubuntu Linux. Your working directory in this case would be MIST under the anaconda directory you chose during anaconda installation.

Alternative Longer Expert Installation Instructions:
1. Download and Install Anaconda with python 2.7 from https://www.anaconda.com/download/
2. Install the Inspyred library by typing the following text in a command terminal: pip install inspyred . For additional details see:  https://pythonhosted.org/inspyred/overview.html#installation
3. Install WxPython library by typing the following text in a command terminal: conda install wxpython . This library is needed for GUI only. For additional details and other ways to install WxPython see: http://www.wxpython.org/download.php#stable 
4. Download the file MIST-master.zip from github by typing the following URL in a web browser:  https://github.com/Jacob-Barhak/MIST/archive/master.zip 
5. Unzip the file MIST-master.zip in a directory of your choice. This will be your working directory. 

To Test the Above Installations:
1. Open a command line prompt/terminal and change the directory to your working directory using the command cd <working directory> - with a simple installation your working directory would be MIST subdirectory under your anaconda installation directory - for example c:\Anaconda\MIST on windows, yet this can be changed by the user, so be attentive. 
2. From the command line in your working directory write the following text: python TestCode.py . It will test the data definitions and algorithms and should take a good portion of an hour - about half an hour on a descent machine. If you got an all caps "OK" at the end, then you installed the python environment correctly. 
3. From the command line in your working directory write the following text: python MISTGUI.py . You should see the Graphic User Interface. If the main window shows up, then the WxPython part is installed correctly. You can try to file->load the file Testing.zip in the InData sub directory to see the examples. 

If you are an expert you can install and setup MIST to work in HPC environment. These expert installations may require professional support. Please feel free to use the contact information below for assistance. 

To run MIST Over the Cloud a More Complicated Setup is Needed:
1. Install StarCluster 
 http://star.mit.edu/cluster/docs/latest/installation.html 
2. Follow the instructions on  http://continuum.io/blog/starcluster-anaconda 
3. If you have not done so already follow the Simple Installation Instructions from above on your machine 
4. Install the nfsshare.py plugin by copying the file  https://github.com/scrappythekangaroo/StarClusterPlugins/commit/775500618279f2fd83e2b7365b5c86cf07e11975 to the StarCluster plugins directory. 
5. Change the config file to include all plugins of interest and add plugin parameters. At the end of setup the "Configuring StarCluster Plugins" section in the config file should have the following lines: 

[plugin anaconda_plugin] 
SETUP_CLASS = anaconda_plugin.ConfigAnaconda 

[plugin nfsshare] 
SETUP_CLASS = nfsshare.NFSSharePlugin 
SERVER_PATH = /mnt/vol0 
CLIENT_PATH = /mnt/vol0 
EXPORT_NFS_SETTINGS = sync,no_root_squash,no_subtree_check,rw 
MOUNT_NFS_SETTINGS = vers=3,user,rw,exec,noauto 

[plugin webapp-packages-installer] 
setup_class = starcluster.plugins.pypkginstaller.PyPkgInstaller 
packages = inspyred  
Also, the plugins should be declared under the section that has your cluster name using the following line: 
PLUGINS = anaconda_plugin , nfsshare , webapp-packages-installer 

For additional information see the following links: 
 http://continuum.io/blog/starcluster-anaconda 
 http://star.mit.edu/cluster/docs/latest/plugins/pypkginstaller.html 
 https://github.com/scrappythekangaroo/StarClusterPlugins/commit/775500618279f2fd83e2b7365b5c86cf07e11975 

6.Use the StarCluster put command to transfer MIST to the /mnt/vol0 directory on the cluster 

It is also possible to run MIST simulations in Multi-core environment using Sun Grid Engine. If you wish to install Sun-Grid-Engine on a single machine for testing purposes:
1. Follow the instructions on  http://scidom.wordpress.com/2012/01/18/sge-on-single-pc/  
2. Follow the Quick Installation for Linux from above 



3. HOW TO USE THE SOFTWARE:

Open a command window and cd to the working directory created during installation then write python MISTGUI.py. The main form titled as 'MIcroSimulation Tool (MIST)' will open. In some systems it is enough to double-click MISTGUI.py to launch the system.

The system includes a help system and an example file to aid in learning how to use it. To get started, select help menu in the main form and then select the help sub-option. This will bring up the getting started help page.

You may wish to start learning the system by loading the example file Testing.zip from within the system and exploring it. The examples there are described in details in the file SimulationExamples.pdf




4. FILES:

The software contains the following files:

~~~~~~~~~~~~~~ Data Definitions ~~~~~~~~~~~~~~
The following files handle the data:
DataDef.py : Defines the data structures of the system.
TestCode.py : A test script that validates the simulation system integrity by running predetermined input examples.
ConvertDataToCode.py : A utility that converts zip file generated by the system to a python script. 
MultiRunCombinedReport.py : A utility that allows combining results from several runs of the same model and population set into a single report. The use of this utility allows running multiple simulations in parallel and combining their results. 
MultiRunSimulation.py : A utility that allows running the same simulation multiple times outside the GUI. Useful for parallel processing on multiple computers. It can be used well with MultiRunSimulationStatisticsAsCSV.py to generate a summary statistics for repetitions. 
MultiRunSimulationStatisticsAsCSV.py : A utility that generates CSV summary reports from several runs of the same project. Combines well with MultiRunSimulation.py that generates input files for this CSV report. The output consists of mean,STD,median,min,max of report columns with regard to different simulation results. 
MultiRunExportResultsAsCSV.py : A utility that generates a CSV file containing the data from a set of result files. 
AssembleReportCSV.py : A utility that assembles a CSV file from multiple CSV files generated by MultiRunExportResultsAsCSV.py 
CreatePlotsFromCSV.py : A utility that constructs plots in a PDF file. The plot data is collected from a CSV file assembled by AssembleReportCSV.py 

~~~~~~~~~~~~~~ Graphic User Interface ~~~~~~~~~~~~~~
CDMLib.py : The main library defining the system GUI
MISTGUI.py : The main file that starts the application GUI with the main form
Parameters.py : The parameters form in the GUI
PopulationSets.py : The population set form in the GUI
PopulationData.py : The population data form in the GUI used by population set
Project.py : The project form in the GUI
ReportViewer.py : The report viewer form in the GUI and called by many forms
ResultViewer.py : The result viewer form in the GUI used by the Project form
States.py : The states form in the GUI
StudyModels.py : The model form in the GUI
Transitions.py : The Transition form in the GUI used by the Study/Models form
Wizard.py : The Cost/QoL Wizard form in the GUI
HelpInterface.py : Defined the help interface between forms and html files in the documentation

~~~~~~~~~~~~~~ Supporting Files ~~~~~~~~~~~~~~
The following files and directories are provided:
README.txt : This file, that you are now reading
License.txt : The GPL license text
DocSrc.texi : The Texinfo source file used to generate the html help files using the command makeinfo --html DocSrc.texi
Documentation : A directory that holds all the html help files
ImagePreperation.odp : A presentation file that is used to generate images for the html help files using the save as jpg.
CopyImages.bat : A batch file to copy documentation images to their proper location to match the html files that form the help system
Temp : A directory containing temporary data generated while the system is running - the system recreates it if deleted.
InData : A directory for input data files - initially holding example file Testing.zip
InData/Testing.zip : A data file generated by TestCode.py and contains simulation examples. The examples correspond to those described in SimulationExamples.pdf.
InstConda : A directory containing conda build files
InstConda/bld.bat : Windows build file for conda
InstConda/build.sh : Bash build file for conda
InstConda/meta.yaml: Build information meta file for conda
SimulationExamples.pdf : A document describing the examples in Testing.zip that are used to test the simulation system. It also contains calculations of the expected outcomes and provide a description of tests carried out in TestCode.py.
SimulationExamples.doc : The original word version from which SimulationExamples.pdf was created.
TestingResults.mdb : A Microsoft Access Database used to test the report mathematics performing the same calculations as the system and outputs files that can be loaded into TestCode.txt. The file contains visual basic code that generates csv files from InputExample.py results. These csv files can then be converted back to code that is merged into InputExample.py as testing code.
ClusterRun.py : A Python script for running multiple simulations with variation overrides on a cluster with some enhancements such as creating plots. This file should be modified before use to fit the cluster it is running on - otherwise it will probably not work.
CodeFromDocAndSpreadsheet.py : A python script that converts rule text from a word document and CSV file from a spreadsheet with populations into code and a model file. This script was created to handle a specific format used with the Michigan model documentation. This file relies on a very specific format of documents and remains undocumented and should be treated as an example for programmers that want to extend the system. 



5. KNOWN BUGS AND FEATURES:

This version contains only simulation capabilities. Note that there are some versions with more advanced capabilities that are not publicly released.

The examples provided with the system are used for testing the system. 

Running the TestCode.py script will test that the simulation system is working properly. Running this file will also create the file Testing.zip that is the data file the system can load and tests the simulation results. The file SimulationExamples.pdf analyses these examples and allows results comparison that is performed when TestCode.py is run. To run this in verbose mode from the command line, change the working directory to the installation directory and type nosetests -s 

In addition to the above test script, below is a list of known bugs and issues uncovered during testing that were not yet addressed at the time of this release:

The GUI was tested on Windows environment and on Linux Ubuntu 12.04. Computations were tested on both Windows and Linux environments through the TestCode.py script. Cloud computations were also tested.

Current issue list can be found on Github issues: https://github.com/Jacob-Barhak/MIST/issues

Legacy Known Bugs:

J0100: WXPYTHON ISSUES ON UBUNTU 12.4 
This issue exists only if trying to build WxPython from source code and not a MIST issue, yet reported here anyway. Fortunately, with conda, there is no need to do this any longer. This issue is resolved on Ubuntu 12.04, Ubuntu 14.04, Fedora 21 Linux distributions. 
At the time of MIST 0.90.0.0 release WxPython does not work on Ubuntu 12.4 since there is a dependency GLIBC_2.15 that is not installed. 
This may prohibit users from using MIST GUI on the stable release of Ubuntu. 
The following command installs WxPython on those systems without need to build:
conda install wxpython -c asmeurer 
Note that other Linux systems have not been tested therefore this issue is not removed from the list. Otherwise the issue has been resolved, especially if using the simple conda installation for MIST.


Comments/Suggestions & Feature Requests:

R0021: LIST OF COEFFICIENTS FOR COST WIZARD
When using the Cost/QoL wizard, the drop down list for coefficients lists states that do not belong to the project. Selecting these states is allowed, but when you try to run the simulation, you get an error that the state could not be found. The error should come while using/closing the Cost Wizard, or the non-included states should not be listed at all. 
INSTRUCTIONS TO REPRODUCE 
1. Use Cost Wizard on a project such as example 1 
2. Add a state that isn't in the selected project, such as Angina for example 1 
3. Run Simulation


J0007: IMPROVE MESSAGES TO USER MECHANISM FOR SIMULATION LOG
Currently a simulation shows messages to the user in a command box behind the windows while preparing or running a simulation. In the future, it would be nice to have a window that holds a log for user messages, possibly with different colors for different levels of information that the user can conveniently browse and study.



J0011: USER CAN OVERRIDE POPULATION REPAIR AND ADVERSELY AFFECT SIMULATION 
The user can create a population with the main process not defined and a state in that sub-process set. If the system option RepairPopulation is set to False, the simulation will end after one time step since the main process will reset all states afterwards. This is unreasonable behavior that should be banned. 



J0016: CONSIDER ADDING STARTED AND EXITED STATE INDICATORS
Considered adding state indicators _Exited , _Started that will contain additional information regarding a state. This will allow assessing which transition was used and if an individual moved from a certain state. Also consider adding special state indicators such as _Duration to keep the time a user was in the state.


J0020: ALLOW BOTTOM UP CASCADING CHANGES THROUGH SPECIAL GUI 

Currently, if a parameter was user by any entity in the system, it cannot be changed. There are work-around solutions that allow creation of copies. However, if multiple entities are involved, many copies of many entities should be created. This increases the chance of human error and it is just cumbersome. Moreover, the problem is not only with parameters, is it with any entity that is used by another entity.
The locks are in place for a reason and the system provides a data to code tool that allows recreating a data base from scratch where this change is present. However, it is still not easy for a user who just wants to go back and make a simple change in a parameter value/formula or even just a note for a state.
Adding a special version of the GUI that will allow making this change through forms just for the purpose of reconstructing a database will be helpful. 


J0030: It is impossible to cancel simulation of population generation from GUI

While running the simulation from GUI in Windows, there is no cancel button that can be pressed to stop the simulation. In some cases, this is desirable and it would be a nice to have feature.

There is a cancel button in the Linux version since version 0.78.0.0.
