Can't load *.mask.pvl.nc file created by Drishti Paint into Drishti Render

[timchaston]

Hi,

I'm having an issue where when I take the *.mask.pvl.nc file I've made with Drishti Paint and try to load it into Drishti Render, it gives me a message "Some problem with pvl.nc files" and displays a volume that is garbled (it's different every time).

I've tried starting from scratch but it didn't help.

I'm using Drishti 2.6.5 on Windows.

Any help would be greatly appreciated!

Hi Tim, The mask files are saved in compressed format, so you won't be able to see them directly in the renderer. Use "Export Raw" option from Files menu to export the compressed mask file to the one that renderer can understand. Cheers, Ajay

Hi Ajay,

Thanks for replying so quickly!

I gave this a go but when I tried loading the the *.rawmask.pvl.ncinto Drishti Render it gave a blank volume (no error messages, though). I guess I'm still doing something wrong there.

I ended up using the 'File' > 'Extract Tagged Region' function to produce a volume file that is good enough for the moment.

Cheers,
Tim

Hi Tim, When you "Export /rawmask" you should get two files file.rawmask and file.rawmask.pvl.nc. .rawmask is the same size as your volume data. Cheers, Ajay

Hi, I have a similar problem.

I exported .rawmask, however file.rawmask doesn't seem to be uploaded in Drishti, and file.rawmask.pvl.nc gives me a blank volume, and mix tag command doesn't seem to be doing anything. I was wondering if I need to be in hires mode for that? If so, as soon as I press F2 Drishti crashes..

Hope for some advice and thanks in advance!
Cheers

Hi Daurica, The rawmask file stores the mask values, so if the mask values you have chosen are closer to 0 i.e. 1,2,3,4... etc, then you will have to move your transfer function closer to the left side - closer to 0. If you don't want to do that then you can just reimport the rawmask volume (rawmask.pvl.nc.001 file) using DrishtiImport - this will remap the values between min and max. Cheers, Ajay
