[Camino-users] schemefile generation

[Ferizi, Uran]

Hello Stefania,


If you asked about how to write a Stejskal-Tanner scheme file, which is a text file, you could use Matlab.


After constructing the matrix, e.g.:

ST_scheme=[directions; |G|;  DELTA; delta TE];

you can write it out via:


scheme_str=strcat('data.scheme');
dlmwrite(scheme_str, ST_scheme, 'delimiter', ' ', 'precision', '%.6f');
% write first line
dlmwrite('output.txt', 'VERSION: STEJSKALTANNER', 'delimiter', '');
% append rest of file
dlmwrite('output.txt', fileread(scheme_str), '-append', 'delimiter', '');
% overwrite on original file
movefile('output.txt', scheme_str);

Subject: [Camino-users] schemefile generation

Hi All,
I have a question about the generation of a schemefile. I have an acquisition scheme like this:

nx ny nz  delta  DELTA  G      TE

0   0   0     0       0          0     30
5   10 0     8       20        80   50
...

with nx, ny and nz as gradient directions.
How can I report all these information in a scheme file? I would like to explicit in the file.scheme the values of delta, DELTA, G and TE. Which schemefile version can I use, please?
The only scheme file version explained in the DTI tutorial is the BVECTOR one.

VERSION: BVECTOR
nx_1 ny_1 nz_1 b1

Thanks a lot
Cheers
