Dear SPMers,

I am wondering which tool you'd suggest, SPM12 Segment using the multiple channels (T1 and T2-weighted data) or CAT12 with only T1w- data (as I understand multimodal segmentation is not implemented here yet).

I notice that CAT12 takes about 4 times as long as the multimodal approach in SPM12.

Thank you,
Best wishes,
Barbara

Yes, providing you are using a recent version. I would strongly suggest using SPM12.

In the user interface, you would specify two channels of information (one for the T1 and one for the T2). Note that both images need to be in voxel-for-voxel alignment first, so you may need to coregister and reslice the T2 to match the T1 (or vice verca).

Best regards,

Dear SPM experts,
I am just wondering whether or not SPM supports multimodality segmentation. I have both T1 and T2 brain images; could/how I use both of them to possibly enhance the tissue segmentation?
Thank you,
Lili
