mean images

Submitted by lena123 on Tue, 10/11/2011 - 01:06

I have the following issues with DPARSFA. I want to start from normalisation step for a set of images that are already realigned and slice ime corrected. I have also obtained mean images for these volumes. But when I try and start unified segmentation based normalisation, the DPARSFA starts searching for mean and does not fine it. It starts computing mean which takes a long time. The mean file is included along with 410 other images in each subject folder (410 time points, 1 mean image = in each subject folder).

Where should I put the mean files?

Hi!
Do not put the mean image along with your 410 other time points in FunImg!
You need to put it under a directory called "RealignParameter" under the working directory. I suggest you to test DPARSFA on one subject with full processing. Then you can learn the structure of "RealignParameter" and make your mean image and rp*.txt compatible with DPARSFA.

Best,
