Hello Bruce,

this seems to be an issue with the documentation. I am using the following syntax:

mri_compute_volume_fractions         reg_file              input_volume      out_stem


That is not included in the documentation. I attempted to use the flags --reg in front of the reg_file_name, --o in front of the out_stem_name, and did not find anything for the input file. Sorry, that got me confused and was basically caused by a type-o in the syntax that I outlined above. It could be usefull to include the above syntax into the documentation. I did not use  mri_compute_volume_fractions for a while and thought something would have been changed meanwhile.

Thanks Joerg

Hi Joerg

can you give us more information than that? Why do you say it is not
possible? It should be

cheers
Bruce
