Dear Chris, 

I have already read the information that you had about ussing custom atlases but the atlas I am trying to add gives still some issues.

I have two atlases (Yeo 2011 for the cerebrum and Buckner 2011 for the cerebellum) loaded as Atlases to use in MRICroGL. What I would like to do it is to change the colors for each network assigned automatically to match the colors that they have in their original atlases:
  1     Visual    120  18 134
  2     Sensorimotor    70 130 180
  3     DorsalAttention   0 118  14 
  4     VentralAttention 196  58 250 
  5     Limbic 220 248 164 
  6     Executive 230 148  34
  7     Default 205  62  78

For this I have created a .lut file using python, with the same name as the atlas and filled in the first 7 rows (with the colors mentioned above) and padded the rest of the 256 rows with zeros. However when I try to load the atlas with the lut file it only shows some random regions in red. Am I missing something important I had to add to the lut file?

Thanks in advance!
