[Freesurfer] MEMPRAGE sequence.

Hi all,We did a scanner software upgrade to BV17 (Siemens) and lost the multi-echo MPRAGE sequence. Does anyone have any idea where to get the sequence? The scanner we have is a Siemens Tim Trio.Any help will be appreciated!Thank you,Zheng Hui

[Freesurfer] New data point for longitudinal processing.

Hi freesurfer,We have processed two time point using freesurfer 5.1.0. I would like to know if we have a third point data, do I need to recreate the base and use this new base to re-process tp1,tp2? Thank you,Zheng Hui ___ Freesurfer mailing list

[Freesurfer] Segmentation of pallidum.

using manual tracing as gold standard. Any comment? By looking at the aseg, there is no intensity change from pallidum voxels and neighborhood white matter voxels. Is the definition of boundary purely based on the probabilistic atlas? Thanks, Zhen

[Freesurfer] Qdec works for Leopard.

[Freesurfer] Total brain volume, correlation coefficient after GLM

Hello all,I have two questions here:1. The summation of all the structure volumes listed in the aseg.stats seems to exceed the Brain Segmentation Volume given in the same file. With the exclusion of CSF and ventricles, the number becomes smaller than the Brain Segmentation Volume. If I am to study
