It looks like just wrong window/level setting in freeview. Have you tried adjust it? You can do it semi-automatically by drawing a ROI with Ctrl + middle mouse button on the slice. On 09/20/2017 12:12 PM, Linnea Marie Dramdal Borg wrote: Hi, My apologies, freeview_T207_dtifit_FA.nii.gz.png

Hi Amanda, I would recommend you to quantify reliability using the same processing pipeline you will use to test for longitudinal effects in your sample. Relevant literature include those listed below. For reliability you would want to evaluate subjects over a time period in which you do not

I don't think surf2surf knows how to deal with patches. We always flatten the individual subject surfaces. You could make a label from the patch and map that across subjects with label2label, then use label2patch to turn it into a patch, then flatten it cheers Bruce On Tue, 19 Sep 2017, Pele

Hi Amanda it really depends what your goal is. If you want to estimate the noise for a power analysis and you are going to process the data longitudinally, then certainly you should use the longitudinal stream to measure the reliability cheers Bruce On Wed, 20 Sep 2017, Worker, Amanda wrot

Hi Fereshte, mris_volume does not create any output files, that number you see in the terminal is the total volume of a given closed surface. Try running mris_volume -v instead and you will see something like this in your terminal: reading ... surface file read in. Volume computation took 0
