I could open up the Brainnetome Atlas GUI on windows but it keeps on giving me an error when I am trying open it up using Matlab on Linux.

here is the Error it gives me:

Error using ==> fgetl at 44
Invalid file identifier. Use fopen to generate a
valid file identifier.

Error in ==> Brainnetome_Atlas at 57
s=fgetl(fid);rror

what could be the problem?
Thanks,
Aral
