Responding re: Douglas Greve

How exactly did you create the LUT? Eg, in windows using notepad? I'm thinking that there might be some hidden characters in there as the color is wrong. I did notice that your first entry had a value of 5 in the last column; usually this is 0 (not sure what it is for). What happens if you switch the LUT to the default? Do you get reasonable colors (even if the names are wrong)?

Reply:

I used a custom python script that creates a LUT for each subject. Then I ran dos2unix to ensure the line endings were appropriate.

If I load the default FS LUT only 2 ROIs are being labeled.

Does this mean that I have an issue with my mri_concat call?

Which is:

mri_concat --sum --f vols.txt --o sub_vols.mgz

Thanks,
