Definition of the parameter maps

Hi,

There are about a dozen Compute commands that create various beautiful maps.  Some of the parameter maps are not self obvious.  It would be great to have a list of definition and literature reference for those maps.  For example, LI map looks similar to FA map, but I could find out what's difference between the two.   The EV map is generated by ComputeEigVecImage, what is each component in EV map?    That information resource would be very helpful.  

Thanks.

Differences between DIFFCALC V3.1.2 command line and DIFFCALC V2.5.1 GUI

I am using TORTOISE V3.1.2. In my shell script I run DIFFPREP and DR_BUDDI_withoutGUI. Then I am supposed to run DIFFCALC V2.5.1 GUI after...BUDDI...  I will not set any flags when using the GUI.
Is the output from GUI V2.5.1 accurate?

I modified the shell script to run DIFFCALC V3.1.2. I am running the following command for DIFFCALC.  Will this command produce the same output that running DIFFCALC V2.5.1 GUI produces? If not, what should I add to this command?

EstimateTensorNLLS -i *drbuddi_final.list

Removing dropped out directions in Tortoise 3?

Hi!

Always thankful for your great software and upgrades!

In Tortoise calcvm 2.5.2 one could click  [display raw images] and delete a volume that had signal dropouts before completing DTI processing. Is it possible to do an analogous operation in Tortoise 3?

Best Regards,
Cyrus

core dump with ComputeGlyphMaps

I'm running Ubuntu kernel: 18.04.3 LTS   64-bit, running in WSL (Linux on Windows). 

I've got Tortoise v 3.2.0, installed in /usr/local, path added.

I'm using BASH as my shell. 

Whenever I run ComputeGlyphMaps, I get "segmentation fault - core dumped"

I've removed/replaced ComputeGlyphMaps. It doesn't seem to be corrupted. 

Other image viewer/editor programs seem to be working fine.

Libpng is installed and is latest version, if that matters. I have dev and dev++ libs as well. 

Any help?
