Dir Sir/Madam,
I am trying to extract FMRI data and having the following problem:
I am using the toolboxes->volumes->multiple volumes->extarct maximum in
order to find a voxel with best activity. Then, while using its coordinates
to plot the data, the two following cases happen a lot:
1) I get a window states that "No row data saved at this location: Data
portions of plots unavailable at this location. Jump to the nearest voxel
with saved raw data?"
2) The coordinates are changed automatically (I guess that it happens when
it finds a close voxels with data).
I wonder why why this scenario occurs? if SPM finds a voxel with maximum
activity, how comes he states that it has no data? Looking at the images
implies that those maximum activated voxels have data, since they have
color, otherthen white.
Is there any way to fix this problem?
Thanks a lot,
