Dear All, I am trying to understand what should be my -fthresh and -fmax or -fmin and -fmax values  while visualizing in tkmedit the significant map of uncorrected results so I can see all the clusters in this map. Further,I want to see what clusters from this map did not survived after correct

Aloha FreeSurfers, I have a small question regarding tkmedit and the line tool. Is it possible to specify start and end point for a line on the tcl prompt? My goal is to create a line in a volume that is not parallel to one of the main axes. ATM I resort to turning the volume in question into

Hi Ray, we do indeed have full subcortical labeling (see Neuron, 2002 paper), but aren't able to distribute it yet. We will do so when able to, hopefully sometime in the next year. cheers, Bruce On Wed, 29 Sep 2004, Ray Fix wrote: Hello Brian, I found this email fascinating because I didn't know

Hello Brian, I found this email fascinating because I didn't know FS had the ability to measure hippocampal volumes. Naively, I tried your suggestion, but found that the mri/aseg directory doesn't exist. How is that normally created? At this point I am using a somewhat archaic (year old ... bu

At this point I have a bfloat volume, that I loaded in tkmedit, and a .label file that contains the resulting ROI. How do I obtain the volume from that? Thanks, George P. On Tue, 28 Sep 2004, Brian T. Quinn wrote: mri_label_volume -s -l will output to the logfile the volumes for each of the

mri_label_volume -s -l will output to the logfile the volumes for each of the labelvalue(s) you list. example: mri_label_volume -s s126 -l s126hipps.log $SUBJECTS_DIR/s126/mri/aseg 17 53 will output the hippocampal volumes for subject s126. -- brian t. quinn On Tue, 28 Sep 2004, George Pap

Hi all, How can I compute the volume of a label created using tkmedit? Is there a program to do this, or is it sufficient to count the number of points listed in the label file and multiply by the volume per voxel? (And if so, is the volume per voxel the voxel size for my original 40 slice axia
