[Mristudio-users] changing .dat file to Analyze file

[susumu]

Hi Afzali,

 

The default format of DtiStudio is "raw", meaning unformatted data without
header. Just a simple string of numbers. If your data is 256x256x41, your
data size must be 4 (float) x 256x256x41. 

 

As Darshan already pointed out, maybe you can try Analyze format. When you
save data by DtiStudio, you can choose the Analyze format.

 

Susumu

You have an option to save as Analyze in DTI-studio the same way you saved
the dat file.

Hi, 

I extracted eigenvalues from DTI data and the results are saved in .dat
format. I want to open them in Matlab. But the figure in Matlab is not true.
I don't know what is the problem. Is the problem due to data or due to
Matlab codes? How can I change the format from .dat to Analyze? 

 Can you help me please? 

I use this commands to open the .dat file. Is it true?    

>>fid = fopen(' EigenVal_0.dat','r'); 

>> x = fread(fid, 'uint32'); 

>> B=reshape(x,256,256,41); 

Thank you very much. 

Afzali.
