You will have to mri_convert all the .nii files so that they have the proper TR.

Hi Doug. I just made a dummy folder with an eccen run. It got around the error XCond = cond(XtX) but took me back to the original error : TR mismatch error despite me re-doing the preprocessing and re- mri_concat-enating my SPM nii files into a 4D file for each run.
Do you think using mri_concat with --regheader could be the problem? Or perhaps the fact that dicoms were converted to nii files in a program that was not freesufer?

Dear Doug,
I am aware I am becoming a regular pain. But I now encounter the following problem when running selxavg3-sess -a rtopy.self.lh -s CMRU1711. I have also attached my analysis.info and Xtmp.mat files
Thanks for all of your suggestions.
