Re: [Freesurfer] epi correction of fmri data
by Douglas N Greve 03 May '13

It should actually run all the way through. If your field maps have the same geometry as your fmri volumes, and your fmri runs have correct geometry, then you can run mri_convert imag_fmap2300.nii imag_fmap2300.geo.nii --in_like fmri.nii Also note that you are just creating a voxel shift map with the epidewarp command, not applying it to the fmri. The application is done in a more complicated way during preproc-sess doug On 05/03/2013 04:10 PM, Corinna Bauer wrote: > hmm. can anything be done to fix it? > > Work the preproc-sess and mkanalysis-sess steps work if I used B0 > corrected images right from the get-go instead of raw fmri runs? > > > On Fri, May 3, 2013 at 4:04 PM, Douglas N Greve > <greve(a)nmr.mgh.harvard.edu <mailto:greve@nmr.mgh.harvard.edu>> wrote: > > yep, it is basically the same error > > > On 05/03/2013 03:57 PM, Corinna Bauer wrote: > > I would imagine so.

determine the peak vertex
by limengsecret 03 May '13

03 May '13

Hi freesurfer, I have a label and each vertex in this label has a probability value. My problem is that how to determine the peak vertex (or the center of gravity) of this label and get the coordinates. And I also want to know, in the tksurfer interface, whether the vertex index has a correspondence to the vertex RAS. Thanks a lot! Best wishes, Meng

Issues with Cluster generation
by Joshua deSouza 03 May '13

03 May '13

Hello all, I am facing a problem whereby after running GLMfit and cluserwise correction for multiple comparisons using the monte-carlo method, I was unable to generate any clusters. I do have significant images produced for the glmfit. All procedures were done according to the tutorial to match the effects under FSGD. There are no clusters available even when I set the cwpvalthresh to .999 which is supposed to show all clusters. What is the cluster generation dependent upon? As my glmfit does show significant areas. Please advise

Re: [Freesurfer] Longitudinal analysis of one timepoint
by Sarah Whittle 03 May '13

03 May '13

Hi, RE the below post, we have longitudinal data from three time points, but a number of participants have scans for only one or two time points. We've done all of the cross-sectional analysis (including a lot of manual editing) and are ready to run everything through the longitudinal stream. Our plan was to run sets of analyses for all of the possible combinations of longitudinal scans. e.g., Time 1, Time 2, Time 3; Time 1, Time 2; Time 1, Time 3; Time 2, Time 3 Obviously the new feature in version 5.2 (i.e., being able to run all images together, regardless of whether some time points are missing for some people) would be MUCH better. Is this possible to do using our 5.1 cross-sectionally processed images? Given the time we've put into manual editing, we really wouldn't want to have to run everything again through 5.2. Thanks, Sarah .... Hi Henk-Jan, to avoid bias between subjects with single time points and others, we run them through the same steps. This way it is possible to include them into the statistical analysis. (For this an artificial base is created with the head in an upright and straight position). This feature will be available in 5.2. Nothing with respect to processing commands changes, you will simply pass only a single time point to the -base and then run it with -long. Nice and transparent :-). Anyway, you probably should wait till 5.2. There is several programs that changed for this to work. Also the current recon-all contains many changes not related to this. If you absolutely cannot wait, let me know and I'll take a look at how difficult it is to go back and adjust 5.1.

Hi FS experts, I tried to run Tracula with the new FS 5.2 release and came across memory allocation problems in the preprocessing step and would appreciate some advice on solving them: MRIalloc(218, 182, 182): could not allocate 158704 bytes for 98th slice Cannot allocate memory Linux daria-Think 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012 i686 i686 i686 GNU/Linux trac-preproc exited with ERRORS at Tue Apr 9 22:21:43 CEST 2013 I attached the log-file. Let me know if you need further information about my system. Thank you in advance, Daria

Flattening a specific surface parcellation or a group of spatially adjacent parcellations
by Bilal Ahmed 02 May '13

Hi, I was wondering if there is a simple way to flatten specific surface parcellations without manually specifying cuts. For example if I want a flattened patch pertaining to the left temporal pole for fsaverage, I would have to manually specify the cut points and then extract and flatten it. As we already know the boundary for this parcellation can we use this information to automatically extract the patch and then flatten it, by providing the boundary points as the cut points? thanks,
