That looks right. You can use 1/6 instead of 1/3, but that will not make a difference in the final p-values On 05/24/2017 11:00 AM, Worker, Amanda wrote: > > Hi all, > > > I have a repeated measures design with two groups (drug and placebo) > and two time points (baseline and follow-up). The g

Not sure what you did. Sound like you found the max vox from the cluster, then extracted the values from each subject and ran those values through the glm to compare p-values against those in the summary file. Right? Now, which values from the summary file are you comparing against? The cluster

Hi all, I'm trying to figure out a way to do create seed-based structural covariance networks through Freesurfer like the one shown in the link below. From the images, it looks like it's done through QDEC. Any tips how to get started? https://ww5.aievolution.com/hbm1601/index.cfm?do=abs.viewAbs

Okay then we’re having an issue somewhere along the line. Using the cache.th40.neg.y.ocn.dat file to make a csv file, we pulled out the individual values and compared across groups using a linear regression in R and didn’t find a group difference for each cluster. Any thoughts as to why that m

Hi Trisanna let's take a step back - what exactly are you trying to achieve? If it is to make a map of the probability that a fold occurs at a specific location then you should not be smoothing at all. And I don't understand why you would be labeling a fold in the volume - why not just label i
