Hi Jon,

I am also confused about this whole discussion. It seems from what you said earlier that at some point you have been able to run freesurfer on your images. You did not use the -i flag back then, but somehow managed to get from the original dicom (via nifti, via some mri_convert command) to some image that free surfer was able to use.

Just do the same thing here and then once that is done, run the base and long stream on top of it.

Best, Martin

I potentially have access to dicoms. My PI was confused as we're using GE 2D dcm images with 126 images per timepoint, he wasn't sure how to have them organized for a test run.

I see now. If the orientation information is incorrect, this will continue to be a problem. It sounds like you have access to the dicoms? If so, it's better to wait and use those.

Allison I'm running the following

recon-all -all -s <subjID> -i path/to/nifti

attatched is the error recon log

I've already gone over this with bruce, martin. It seems as if the 001.mgz, orig.mgz, and orig_nu.mgz all have incorrect orientations. This is coming straight out of the nifti files I've passed and these mgz's are generated before the recon-all process exits with errors.

In short, the answer is yes. The 2nd and 3rd steps will take the subject ID and find the relevant files. But I would expect the first step to take nifti just fine. Can you send the command you are running?

As I'm having trouble importing nifti files into the first step of the longitudinal work flow, I'm wondering if I can use volumes generated from recon-all -s <subjID> for the second and third steps of the workflow.
