Re: [Freesurfer] how/where is talairach.xfm used?

Hi Mike, it is used a bit in mri_fill I think, although it might actually have been removed now that we use the aseg. There is also the option of using it to initialize the spherical morph, but that is disabled by default, so it's not used very much. Generally as long as it's not dramatically

Mike, I think it is perfectly acceptable to use the talairach.xfm file generated for a subject by v4 for use with v3.0.5 processing. There is no difference in the file format, it is just more accurate. Another feature in v4 is a check of the talairach.xfm file against a set of known-good alignme

Yes, based on a small N, version 4 does seem much more robust. So, if we wanted accurate .xfm's without requiring manual editing, would it be appropriate/fair to use v4 for autorecon1, but then use v3.0.5 for autorecon2 and 3, so as to maintain compatibility with other data processed under v3? t

Is talairach.xfm even used as input for any stage of autorecon2 or 3? (Or, is it just the talairach.lta and talairach.m3z files?) thanks, Mike H. On Thu, 2007-10-11 at 16:28 -0400, Doug Greve wrote: > It is not that important from a recon standpoint. However, if you intend > to report talairac

The --paired-diff options just take the difference between adjacently specfied inputs. You then set up your design matrix or FSGD file and then run mri_glmfit. The --help for mri_glmfit has a lot of info about the glm analysis. If you just want to test whether the difference is 0, you can use
