If you prefer working in MATLAB: Osprey can handle SPAR/SDAT data and will automatically create voxel masks and PDF outputs for you. @Helge also recently added a function that transforms all voxel masks into standard space and gives you an overlap plot.
Dear experts,
I’m trying to run osp_plotVoxelOverlap on my data. I’m running MEGA-PRESS data through the standard Osprey pipeline in a release downloaded Monday, Feb 13, 2023.
Currently the output looks like this:
[GABApaper_voxeloverlapfigure]
The heatmap looks OK, but two of the three views are on the wrong slice. It looks to me like the center of mass of the voxel mask may not be setting up correctly in osp_extract_three_plane_image_overlay. Is there an easy fix for this?
I’m happy to p…
Hi @Wang ,
Thanks for reaching out.
If you want to use the osp_plotVoxelOverlap function you have to run the following steps:
MRSCont = OspreyJob('PathToYourJob.m');
MRSCont = OspreyLoad(MRSCont);
MRSCont = OspreyProcess(MRSCont);
MRSCont = OspreyCoreg(MRSCont);
MRSCont = OspreySeg(MRSCont);
or the equivalent GUI buttons.
In the jobfile you should include the MRS data and T1 images in subject space. And you have to make sure that there are no SPM segmentation results from a prior SPM/Osprey …
