Hi there!
Will be grateful for your advice and I believe you will know the answer.
I have two sets of data from two separate scans. The previous scan I used the Bold data in +orig space I got from preprocessing the data and I used this in a deconvolution along with a mask I obtained from 3dAutomask on the preprocessed data. The resulting SPMs were then laid on top of the tlrc anatomy with excellent fit. We did a second scan on the same person at a later date and tried to analyze the same way but this time using the tlrc volume from the first scan since we didn't collect a second volume because we thought we could get away with using the +tlrc Volume from the first. They didn't overlay well and the masks from each were very different. My question is is there an accurate way to overlay the second scan +orig data onto the second scan +tlrc volume and how would I do that?
I would appreciate your advice.
Thanks,
-Linda
