Hi Bruce, The template is the ICBM 2009b nonlinear template (0.5mm isotropic) which I downloaded from the McGills site ( http://www.bic.mni.mcgill.ca/ServicesAtlases/ICBM152NLin2009). The template has a range of values from 0-100. Then I combined the csf/wm/gm masks (derived from the 2009c tem

[Freesurfer] Question about Qdec

Dear experts, I've been attempting to generate a stats data table in qdec, but each time I get a "Index Error: list index is out of range" error. This is occurring when it is trying to parse the .stats file. I've made sure that the files all line up exactly with the qdec table and that SUBJECTS_

Re: [Freesurfer] converting labels to MNI space

Try adding --invertmtx to the mri_label2vol command. I don't think the label2label command does anything, does it? Also, you might have better alignment if you run recon-all on the mni152 brain, then use mri_label2label to map the label from the individual into the 152 space using the surface t

Re: [Freesurfer] Sign option of Monte Carlo simulation in QDEC

2015-12-01 Thread Douglas N Greve
By default, FS uses unsigned (ie, two sided) tests. If you have an a priori hypothesis about the sign, then you can use a signed test. When you use a signed test, the p-value is that of the unsigned test divided by two, ie, it is more significant. When you specify a sign for the MC correction,

[Freesurfer] Sign options of Monte Carlo simulation in QDEC

Dear Freesurfer experts: we would appreciate if anyone could advise on the sign choice of Monte Carlo simulation, a question we posted 2 days ago. In examining QDEC results of a contrast of interest, we noticed the results are mainly in cold color (blue), with only two small clusters in warm

Hi Ajay can you explain your entire processing stream, including the details of the acquisition? What sequence/coil/scanner was used? You could fix your problem by looking at the defects on the inflated.nofix, overlaying lh.defect_labels on it to see where they are, then figuring out what cause

Hi Bruce, When looking at my top slices in brain ask I noticed that the gray/white matter shows but the darker areas surrounding it are not present (this usually goes to the edge of the brain). Could the large defects be a result of having masked this out on the input file? I multiplied the tem

Hi Falk I don't think you need to rerun the qsphere. I'm pretty sure this is a bug in mris_fix_topology for giant defects, but haven't finished tracking it down yet cheers Bruce On Tue, 1 Dec 2015, Falk Lüsebrink wrote: Hi Ajay,   you should   cp ?h.orig.nofix ?h.orig cp ?h.inflated

Hi Ajay, you should cp ?h.orig.nofix ?h.orig cp ?h.inflated.nofix ?h.inflated with ? being l or r depending your hemisphere. After the fixing stage the surfaces got damaged somehow, therefore you have to recreate it them. I’m not entirely sure about the qsphere. Probably you have to run the -q
