Hi
I am processing DTI data using eddy, followed by fdt and bedpostx in FSL 6.0.0. FDT runs as expected but bedpostx gives the errors:
eig_sym(): failed to converge
Mat::operator(): index out of bounds
The images in eddy.nii.gz appear normal, at least there's no obvious corruption. The only odd thing is that the data type is changed from int16 to float32. I ran another data set successfully, and this also had float32 output from eddy, so I'm guessing this is normal.
I'm using autoptx to run everything, but am testing using bedpostx on its own too. I think bedpostx runs OK on the data before eddy. Am double-checking.
Can anybody suggest how I can get bedpostx to run on my eddy-corrected data?
Thanks
Paul Wright
