Dear SPM users

Please please I need your help. 
I want to create a piriform mask to use it as a seed for functional connectivity analysis. I could not find the piriform structure in any of the atlases provided by WFU pick atlas. Does any one have an idea from where or how can I create a piriform cortex mask??

Thanks

The images need to be in the right format before you begin.  I'd suggest using the DICOM button of SPM to generate the NIfTI files so that the orientation information is filled in correctly.

Registration in SPM involves a local optimisation.  This means that you need reasonable starting estimates - ie approximate positioning information in the headers.

Best regards,

Hi @all,

some how the cogistration fails, because it seems that the x-direction of the structural image is just in the wrong direction. I don't know why this happens and what's the problem. I attached an image, maybe some of you have an idea how to fix this.

Thanks in advance
