Dear all,
hopefully someone can help me with the following problem:
I have a series of scans from patients that were scanned in several years time. All T1 series were coronally scanned. Most T1 scans are in 256x256x120 matrix, but some of the later scans are in a 512x512x120 matrix. I'd like to use the sienax script to do both grey and white matter segmentation.
For the 256x256 scans this goes fine, but I face problems with the 512x512 scans. Somehow the alignment to the MNI standard brain goes awry. The whole sienax script is run without any errors appearing under the command line, but only a small part of the brain is segmented, because the standard-mask is wrongly created.
To make the final outcome a bit clearer I uploaded the I2std.png and I_masks.png for both a 256x256 and a 512x512. They can be found at:

The files appear in the left bottom after 10-15 seconds. Don't push on the add-download button.
Does anyone have an idea how I can solve this problem?
