You can generate a surface from the hippocampus by first running recon-all on an anatomical image, then using mri_mc to tessellate the left and right hippocampi. cheers Bruce On Tue, 22 Feb 2011, Saad Shakeel wrote: > > > > From: saad.ak...@hotmail.com > To: fsregis...@nmr.mgh.harvard.edu; fr

Try loading it with the surfaces (add -surfs to your tkmedit cmd). It may be on the surface at that location. doug Fernanda Palhano wrote: > Hi Doug, > > Thanks for the command, it worked well. > But, I still have a problem. The overlay seems to be misplaced. > I'm sending a .png with an example

It should be the case that the clusters in the 2.3 should be clusters in the 1.3, but there p-values will be different. It is possible that a cluster that is sig in the 2.3 is not sig in the 1.3, particularly small clusters like the two you have shown. Small clusters may be very likely at 1.3 u

2011-02-22 Thread Douglas N Greve
I assume that you are comparing maps of Version1:1v0 and Version2:2v0 ? I could imagine it going either way. If the true slope is 0 but the offset is non-0, then Version1 will give you an artificially high slope (and Verion2 will give you the correct slope at 0, and so no activation). Are you c

This is not my understanding. It is completely dependent on the threshold used, which can be arbitrary. See Supplemental figure 7, page 16 of this document: http://www.jneurosci.org/cgi/data/30/6/2268/DC1/1 This was the motivation for Smith & Nichols' TFCE: http://www.ncbi.nlm.nih.gov/pubmed/1

You should also look at Version2:1v0. I bet a lot of the areas from Version1:1v0 will also show up. You can also create a Version3 in which you divide your presentations into a low-weight and a high-weight (but set the weight=1). Then create contrasts of low+high and high-low. The low+high shou
