Hello Luis and Donald,
<div><br>
</div>
<div>Thank you both for the responses. I did come across mrtrix documentation regarding the compatibility of FSL gradient tables (which is what I was attempting to use and could be the source of the error message I received). I will check the 'transform' entry
using mrinfo to determine if the real and image coordinate systems are equivalent. If not, I will try the KK Gradient Table creator. Thank you for reminding me about this code, I had forgotten about it. I will let you know if there are any further issues.
Thanks again.</div>
<div><br>
Best,</div>
<div>Michael<br>

</div>
<div></div>
<div>In PAR/REC version 4.2, this is in one of the columns after the tag ===IMAGE INFORMATION===. The header of that huge table will tell you which column tells you the information (diffusion (ap, fh, rl)) and is a three-float number. Similarly, the b value
is in the column labelled diff..

Hi Michael,
<div><br>
</div>
<div>I've no experience with Philips PAR/REC data, but a quick Google search gives a lot of suggestions. For example, the first hit when searching for "PAR/REC Philips gradient" sounds pretty relevant:</div>

<div><br>
</div>
<div>Is there an easy way to find out the [X Y Z] components of the gradient direction for PAR/REC images from a Philips 3T Acheiva scanner? It is no problem to get the magnitude of the directions and b value from the PAR file but I am unsure how to extract
the correct component values. Thank you in advance for any information.</div>
