[Brains-users] Problems with tissue class models and linux paths

[Kevin Berne]

Hello,
After my request last week I have installed the recommended Brains2 DEBUG 2005_09_05 as well as an up-to-date Cygwin environment. This resulted in a much smoother operation without the troublesome inability to create a standard directory. Nevertheless I have encountered more difficulties, which as a linux novice I have tried but failed to solve alone.
First of all, whenever I try to run a segmentation to create a tissue model, the process fails after writing the plugs, displaying an error message expressing either the inability of creating the model or loading certain masks. This occurs in several forms whatever options I seem to choose within the dialog boxes.
Furthermore, one certain error message keeps popping up whether I try to run a segmentation or a neural net, reading "Error: chgrp: invalid group `stdwkup´. I have tried to conduct my own internet-research, but since I do not have any experience with linux-based operating systems I can not make sense of what I mostly find.  I would gladly appreciate any recommendations or tips anyone could give me about this particular malfunction.
Thank you very much for your time,
Kevin Berne
