Hi Doug,

I'm not sure why that does not make sense, shouldn't the input of mri_concat be several to-be-concatenated files rather than a single file?

Sorry, I did not mean to imply that the command line was wrong, rather that the behavior did not make sense -- it should print *something* to the terminal. It does make sense to have multiple files, but it will also work with a single file. I just suggested this to make things simpler.

Anyway, after trying out the command with only one of the files from the tutorial,

/mri_concat --debug /media/Dell/_FS/buckner_data/subjects/140/surf/lh.thickness.fwhm10.fsaverage.mgh --o /media/Dell/_FS/buckner_data/subjects/qdec/y.mgh/

..the same thing happens, namely it returns to the command prompt, with no message whatsoever.

What could be wrong? As I mentioned, all those MGH files are at the expected path. Thanks again for your help!

What happens if you type mri_concat with no options at all?

That does not make sense. Try using only one input file. Also, put
--debug as the first option.

Hi Tudor,
Can you run mri_concat from the command line with the --debug
option
first. Send us the FULL command line and the full terminal
output.
