[Mristudio-users] XP laptop and vista usage

[susumu]

Hi Jim,

 

When memory shortage happens, usually DtiStudio clashes. It doesn't give
wrong FA maps, I believe.

Do you mean the same dataset can be processed in one computer but not in the
other?

 

To check the memory issue, as I mentioned in the previous email I sent this
morning, you can use "Slices to be processed" window to specify only few
slices to be processed. If this gives you correct FA maps, but not when the
entire slices are processed, then it is definitely the memory issue.

 

The most common mistake that would give strange FA maps is typos and syntax
errors in the gradient table. Again please refer to the email I sent out
today.

 

Susumu

My problem with DiStudio appears to be main memory related.

I get bad data on the FA map with all values of FA 0 or .7 and higher 

on one machine the problemgoes away when I remove other memory users. 

 

I would like to know if there is a way to flag memory shortage other than
obvoiusly bad data.

 

I had a memory limit warning using ImageJ with a link for help.

But with DtiStudio, I just got snowy or blizzard covered images. 

 

Will try more. 

I have an idea for using the 16x16 array for finding the best contiguous
area

which fits a required ROI size.
