[Mristudio-users] urgent help

[Dresner, Alex]

Dear Supreet Kaur,
Most often a color map problem indicates something is wrong with the gradient table that was entered.  Two easy problems to fix are that your DTI data may not be in Slice-By-Slice rather than Gradient By Gradient (button, top right of DWI Parameters window) or that your gradient table may be rotated or flipped, so that the columns do not represent the right x, y, and z directions.
Good luck,
Alex

Subject: [Mristudio-users] need urgent help!!!!!!!!

hello Hanygi,

            I am working on the fiber tracking in DTI studio. I am facing a color map problem.
The data was initially provided in the (brain_data_1.iso.ni<http://brain_data_1.iso.ni>) NIFTI format, I converted it into the (.REC format). Then I loaded
it in the DTI studio and did the DTI mapping and calculated the Tensor, color map, etc.
The color map images are coming out to be terrible...as you know that the color map images are imporant in fiber
tracking;
Could you please provide your valuble feedback on this..I am attacking a word file as I took some shots if those images
and also providing you with the image parameters.
I'll appreciate your help.

Sincerely,

Supreet kaur
