Convert tutorial

Step1 Prepare the followings

• MATLAB2013b

• homer2

• Shimadzu2nirs

Step2: Set the path

Set homer2 in the path of MATLAB2013b.

Step3: Open the SDgui

• Set your work path at D:\toolbox\homer2\PACKAGES\SDgui (change the path in the computer)

• Run SDgui.m in MATLAB2013b.

• Next, a prompt will appear for you to select a file. Simply click "Cancel" to proceed.

• Then you will see this.

Step4: Create the SD File

• Base on your optodes arrangement to fill in the blank in the sources and detectors.
  • Note: z is always 0.

• When you complete setting the sources and detectors , then click the number, you will get the channel.

• After setting channels, and you need to fill in the “Lambda” based on your data acquiring device.

• Provide a name for the SD file, and let's call it "test.SD," including the ".SD" suffix.

• Click the ''Save", and in the new window, you need to choose the "units", here is "mm"

• Your SD file is saved successfully ! Just close the SDgui.

Step5: Convert!

• Put the data need to convert (.txt), 3 files from Shimadzu2nirs.zip and test.SD created in step 4 together, and set the MABLAB work path to them.

• Run the Shimadzu2nirs.m, then you will get the .nirs data file !

The common error

If the optodes arrangement of your experiment is as follows:

Then your SD file arrangement must correspond one-to-one:

If the arrangements are totally inconsistent, for example:

The error will be:

If the arrangements are consistent but the channel numbers in the SD file are inconsistent, for example:

The error will be:
