[Camino-users] Error using datasynth for crossing fibers

[Jonathan Rafael Patiño]

Hi Prasanna.

In case that you are still having troubles with the simulation, the
​ problem
 is almost the same as in the thread:
http://www.nitrc.org/pipermail/camino-users/2014-October/000432.html.

Basically, you are using a BVECTOR format which cannot be parsed from the
function datasynth. Also, as far as I know, datasynth
​w​
on't parse the parameters
​​
-G 0.022 -del 0.032 -DEL 0.04,
​as ​
they need to be specified in the scheme file.

The resulting scheme file for a
​​
Stejskal-Tanner sequence
​, with values
​
G
​=​
0.022
​,​
del
​=​
0.032
​,​
DEL
​=​
0.04
​ and TE=0.08,​
 should be
​somewhat like ​
the one
​I​
'm attaching.
​

Here's the
main

scheme files information page:​

​Best​!
