Hi,
I have to bring up an issue again which we had some discussion about before, but which we haven't yet found a satisfying solution. I would like pose my question a little more precisely again: 1) I have a dataset that is in 181x217x181 coordinates. 2) I am processing it as follows:
mri_convert name.img name/mri/orig/001.mgz recon-all -motioncor -subjid name
3) after step 2, the resulting dataset is somehow transformed to a 256x256x256 dataset, i. e. the 181x217x181 is embedded into the 256^3 array: it is rotated and the origin in 181x217x181 is not the origin in the 256x256x256 array. 4) Since I would like to do a voxelwise comparison between the recon-all result and my initial dataset 1), I need to backtransform the result into the 181x217x181 coordinates (and of course, the backtransformation should be the exact inverse of the transformation in 2). I haven't found any info about how this transformation is done by FS, mri_info does not provide it.
Thanks, Frederick
