[Mristudio-users] saving files

[susumu]

Hi Sarah,

This happens when one of the boxes in "Image Dimension" and "Voxel Size" is
"0". Please check.

When you are reading "Raw" data, you need to know the matrix and pixel sizes
and provide these numbers in these boxes.

When you are reading "DICOM" or "Analyze", the information is provided from
their header files. So, these boxes are inactivated. There is one silly
issue of DtiStudio, which is that it doesn't like "0" in any of these boxes
even if DICOM or Analyze data are used. Please input non-0 number in these
boxed before you choose "DICOM" or "Analyze" and the boxes are inactivated.

Thanks, Hangyi -

I have tried to do this before when loading data files, and tried it again
as you suggested. I get the message "please enter an integer between 1 and
4096". I don't know where to enter an integer, or which to enter, but I've
tried all options and still get the same error message.

Can you help?

Thanks  again -

Sarah



hi,

after saving, you can re-load the image by "File->MRI View 3D->..->
File_Format=RAW, Data_Type="Color" (for color map), or  Data_Type="float"
(for FA etc..)...-> OK"

regards,

hangyi
