Dear freesurfers,
After executing recon-all with -autorecon1, I opened the image Barba50527_2 *T1.mgz* from tkmedit. The bad resolution leads me to doubt that my input format wasn't correct.
I input two sequences of images. Each image resembles the attachment Sample Input. There are 439 such image in each sequence.
Would you please shine some light on my bad resolution?
Thank you very much!
Sincerely, Ye
Hi Ye,
it's impossible to tell anything from the first image, but the second is definitely not a T1-weighted anatomical. You need to talk to someone who knows something about the acquisitions, otherwise you are just spinning your wheels and wasting time. You won't be able to analyze the data unless it is T1-weighted with voxels that are <1.3mm or so in any dimension. This is routinely acquired, but you need to confirm that it was. You can run mri_info on the dicoms to find them, but talking to someone who knows the protocol will be a lot faster, easier and more accurate
cheers Bruce

Dear Bruce,
Thank you very much!
Sincerely, Ye
PS: I hope they get back to me with the T1-weighted images.
