External Email - Use Caution        

Hi Kersten,

If that's alright with you then that would be great. I completely accept if my threshold is accurate and leaves no significant findings, I just can't find a comparable threshold on this forum or elsewhere with such an elevated threshold value.

I can touch base next week to see what you need from me.

Thanks again,

Dan

Hi Dan,

I can see no obvious issues at the moment, but am happy to take a closer look when I am back in office next week. 

The fslmer tool ist just an R Implementation of the Matlab scripts, so I don't see any need to use them in your case.

Best,

Kersten

Hi Kersten & Martin,

I just wanted to ping this thread again, as I'm still unsure about my pcor value (4.4) that I'm getting. I've seen other posts where the threshold (thmin) value specified in functions such as mri_surfcluster are around 2 (corresponding to a p-value of 0.01) when threshold *sig.mgh file(s). Given that I'm interested in both right and left hemispheres, I'm surprised that my single threshold value to account for both hemispheres is so high relative to others posts I've come across in the forum. I seem to have followed the LME approach correctly (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/LinearMixedEffectsModels) but I'm unsure if I've done something that has resulted in an elevated pcor value. 

Martin had recommended the fslmer tool (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://github.com/deep-mi/fslmer), I'd be happy to use that instead if it's more current and the preferred tool for this kind of analysis. 

Thanks again,

Dan
