[Mristudio-users] recalculating means with two AIR series?

[Elizabeth Finger]

Hello-

I have a large DTI data from GE in dicom format set that contains 3 B0 images plus 33 gradients, 50 slices, and two separate runs per subject.  I am able to pull up both runs  in DTI Mapping and to run the AIR. However, when I try to then calculate the means and STD for multiple runs, I run out of memory, as I do when trying to do the tensor calculation directly.  I am able to proceed if I process just one run at a time. However, if possible, I would like to use the mean from the two series (it was from children, with a lot of movement and fair amount of scanner artifact).  I have tried to save AIR files as raw and analyze format, but am only able to open up the analyze format in MRI 3dview, and not in DTI mapping (for the raw formats in DTI mapping, when I attempt to load them, it say "number of files in this fold is less than expected".   Is there some way to load just the AIR files into DTI mapping to use for the means recalculation and tensor calculations?  

Many thanks,
Elizabeth Finger
