Dear relax community, 

I am a new user that recently installed relax 2.2.2. After been playing around 
with it I spot in the late stage of my final calculation the following message 
in attach.

Does anybody has a clue or advice what could be wrong with it. I spot a similar 
error in earlier relax versions (bug #12408) but I am not sure if it is the 
same issue, apparently relax can't read/load my diffusion tensor. 

Any help will be appreciated.

Many thanks,
Angelo
