[Freesurfer] registration problem

2014-11-14 Thread SHAHIN NASR
Hi, For one of my subjects, I have noticed a misalignment between sig.nii and orig.mgz when I try to show the sig map using either tkmedit (as below): cd /autofs/cluster/tootell/pitcairn/1/shahin/V2_Ori/Analysis tkmedit-sess -s ../Subjects/auil2 -a OriExp_TR3_1p5mm_PR -c ANG_90_45 or

Hi experts, When I'm pre-processing the 4D whole brain BOLD images using preproc-sess -sf -mni305 -fwhm 5 -fsd bold -per-run , the results of registration from BOLD images to the MNI305 template are always only a small part of the original images. I tried to use another T1_152 template

Hi Rebecca, this is intentional. The whole brain is divided up into left cortical hemi, right hemi, and subcortical structures. the MNI305 is only supposed to handle the subcortical structures. If you want a brain volume with cortical and subcortical, you can use vlrmerge to merge the

Hi Rebecca, have you verified that the registration to anatomical space is correct? doug On 07/02/2013 08:09 AM, Lijia Wang wrote: Hi experts, When I'm pre-processing the 4D whole brain BOLD images using preproc-sess -sf -mni305 -fwhm 5 -fsd bold -per-run , the results of registration

Hi, I have 3 contrasts between conditions in a between group comparison on the volume, and I'm using mri_volcluster to get information about the data. For some reason, while two of the contrasts (ASvfix and ASevASc as shown below) are compatible with the register.dat file for these

how did you create BwGroupError5/bold/EMerror/tal-rfx/ASevfix/sig? It is 64x64x20, which is probably your native functional space. Robert Levy wrote: Hi, I have 3 contrasts between conditions in a between group comparison on the volume, and I'm using mri_volcluster to get information about

Hi Doug, These are the commands that were used, or so I gather based on the file dates. Shouldn't this have put them into a common talairach-based space? #kthakkar 1/16/06 #*ASD v. Normals volume analysis* intergroupavg-sess -analysis EMerror -contrast ASvfix -group1 BwGroupNormalsError5
