Hello Freesurfer developers,
I am interested in analyzing PET data following a longitudinal design. I have co-registered each PET image to the closest MRI in time processed through the longitudinal stream. I have sampled each co-registered PET image time-point onto fsaverage surface via the individual's subject surface (mri_vol2surf).
From this point:
1. Is it possible to obtain spc (symmetrized percent change) using long_mris_slopes for each subject?
2. Is there a way to input the sampled surfaces into a qdec file for long_mris_slopes command?
1) FreeSurfer version: freesurfer-linux-centos6_x86_64-7.2.0. 2) Platform: Ubuntu 18,04.6 LTS 3) uname -a: Linux ubuntu 5.4.0-122-generic-Ubuntu UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Thank you!
Jesus
