<div dir="ltr">Hi MVPA users, <div><br></div><div>I am trying to perform multivariate analysis on multi-modal data (T1, FLAIR, and PET). All have been warped to MNI space and resliced to 2mm isotropic voxels. I may be wrong but I haven't seen much documented on the website integrating multiple modalities into an mvpa analysis. (I have seen separate analysis of different types of data (fmri or meg) but not integrated into a single dataset/analysis).</div>
<div><br></div><div>Currently I have stacked the images in the Z direction into one nifti file using fslmerge. I also had to stack 3 copies of a brainmask in the Z direction to properly mask out the brain regions. Originally, I had thought of just concatenating the data into time dimension so that I could use a single mask - but I am not sure if this is appropriate or not. The other reason for not using the time dimension is that I would like to add TBSS data from fsl into the analysis which would necessitate a different mask (something that I could do if I stacked the data in the Z direction).</div>
<div><br></div><div>The data is reading in correctly and preliminary analyses seem to be working. I know that this is not an optimal solution. Is there a better method already packaged into mvpa? </div><div><br></div><div>
<br></div><div>Thank you,</div><div>Jeff Stout</div></div>
