Dear all, I am very new to caret ( and to the list of course). So please excuse me for asking a question that has been debated a number of times on the list.
All I want is to know if the procedure that I am using for mapping my functional images from SPM8 (spm_t images) ( in MNI space) to PALS atlas : Human.PALS_B12.BOTH.TEMPLATE-for-fMRI-MAPPING.73730, is correct or not. What i am doing is the following (based on the sep06 caret tutorial on the web http://brainvis.wustl.edu/CaretHelpAccount/caret5_help/tutorials/Caret_Tutorial_5.5.html) : (and please correct me if there is anything wrong there) 1. Opening the spec file: Human.PALS_B12.BOTH.TEMPLATE-for-fMRI-MAPPING.73730.spec 2. Renaming it to a different name. 3. Using Map Volume(s) to Surface(s), using metric data. 4. Selecting my .hdr images and then using the option Map to Spec File with Atlas. 5. Selecting my newly named spec file and using space as spm5 and atlas as the PALS atlas for left and right. 6. saving the metric files and using metric enclosing algorithm. 7. For visualisation, I open the spec file. load the file and in D/C I use overlay/underlay data type as metric. 8. For threshold, I use the metric settings and user threshold. I want to confirm if the 'atlas and SPM5 space' options take care of the registration (and I dont need to register my functionals or structurals to caret atlas). In other words, what space is Human.PALS_B12.BOTH.TEMPLATE-for-fMRI-MAPPING.73730 in? and is it the same as for SPM8?
