You can try putting all the runs into a single bold directory. The
motion correction will (do it's best to) align them.

Hi
My question was asked last year by Tommi Raij (see email pasted below) but I
couldn't find a reply to it in the archives. I am analysing retinotopy data
that was collected over several sessions but I cannot see how to register
scans from multiple sessions together, and to the subject's anatomical scan.
Although Fs-Fast appears to combine the data from multiple sessions during the
retinotopy analysis it only seems to be possible to use one registration file
(register.dat) when overlaying the results onto the anatomical. I would have
thought that registering scans from multiple sessions together would be a
feature that many people would require. Is there anyway to do it? Tommi gives
some possible methods in his email below.
When I do try and overlay my data onto a surface I see 'gaps' in the
blue/yellow colouring of the fieldsign map overlaid onto the cortical surface.
I wonder if this could be due to the inaccuracy of the registration given that
I only used the register.dat from the registration of the first session.
hope that makes sense!
i'd be grateful for any help with this!
Jane
