Thanks for getting back to me. I suspected the scheme file warning was
cosmetic, but will try the newest version when I get a chance. I've
tried order 8 and it hasn't improved matters.<br>

<pre wrap="">Hi Ian,
I believe we have fixed the issue with sfpeaks complaining about scheme files in the current version. I am unsure if this is related to your problem. It seems most of the data from sfpicocalibdata is being mapped to a similar place in the LUT for some reason. This could be a problem with sfpeaks, but I'm not sure.

<pre wrap="">Hi,
I'm trying to use a QBall SH reconstruction with Pico, but am hitting a problem at the sflutgen step. Not sure what's causing this, SH order is too low maybe? The scheme file has 64 unique DEO, steps were:
qballmx -schemefile DWI.scheme2 -basistype sh -order 6 -normalize > qballMatrix_SH6.Bdouble
sfpicocalibdata -schemefile DWI.scheme2 -infooutputfile A.info > PICo_data.Bfloat
linrecon PICo_data.Bfloat DWI.scheme2 qballMatrix_SH6.Bdouble -normalize > calib_ODFs_SH6.Bdouble
sfpeaks -inputmodel sh -order 6 -numpds 3 < calib_ODFs_SH6.Bdouble > calib_ODFs_SH6_PDs.Bdouble
- complains about not having the scheme file.
sflutgen -infofile A.info -outputstem SH_lut < calib_ODFs_SH6_PDs.Bdouble -pdf bingham
