[Mristudio-users] bug in DTIstudio 3.0 (beta) tensor calculation?

[Yi Jiang]

Thank you very much for your help. However, I always work on the same computer, where I can get good results for a 1 b0+12 DWI dataset, but not the 1 b0 + 6 DWI dataset, using the 3.0 version. It seems to me the former should take more memory?

Best,
Yi

  You and I may share a memory problem. 
  Using the same dti series b0+6 dir images from several MRIs I have 
  bad FA maps but pixel value distribution is 0.72 to 1.0 on my laptop with limited 
  paging maemory, apx 1.2 GB.

  It works on another laptop (newer vista )      

  The problem for me is on one laptop and one office PC in a research room.
  But not on the 2nd laptop or another PC in the same research room which is 
  the same as the other desktop except for the wide screen and graphics card.

  It would seem that there is a paging issue or paging space because you may get around it if you clean up files in the paging area 
  desk top items - pictures or music files which use us virtual memory.







  Thanks                  Jim Neeley,
