CONN output space different from input space
Hello,

I was viewing my results and I wanted to extract the mask of a significant cluster. After clicking the "Export mask" tool, I noticed that the [given_roi_name].nii had the dimensions 74x92x78. When I opened the CONN files in SPM and extracted the cluster through SPM instead, the dimensions of the cluster mask were 91x109x91, which I believe is the standard MNI output space . 

Both of these output spaces are different than the original space of my input images (MNI152NLin2009cAsym, with dimensions of 97x115x97.

My question is: Does CONN resample the original input images to be in MNI space? Is there a convenient way to convert the output images back into my original input space? I found a way using AFNI's 3dresample, but I was wondering if there was an option to do this within CONN.

Additionally, why was the original cluster mask using CONN's "Export mask" tool in a different space than MNI space?

Thank you for the clarification!

Best,
Ryan
