Dear FSL users,
I just ran bedpostx and following it's completion, I received a message stating "for some reason the bedpostx process DOES NOT appear to have successfully completed. Please examine your results carefully."
First thing I did was load both dyad1.nii.gz and dyad2.nii.gz into FSLview. I looked over the tensors using the RGB option. The dyad1.nii.gz file looked to be alright; however, dyad2.nii.gz looked a little off to me when I used the lines (RGB) option. I attempted to upload the two dyad files, but the message exceeded the limit.
Following this, I used FSLinfo to get the information from both dyad files and the data.nii.gz file I created in DTIFIT prior to running BEDPOSTX. Below is that information:
data.nii.gz
data_type FLOAT32
dim1 128
dim2 128
dim3 70
dim4 33
dyads1.nii.gz
data_type FLOAT32
dim1 128
dim2 128
dim3 70
dim4 3
dyads2.nii.gz
data_type FLOAT32
dim1 128
dim2 128
dim3 70
dim4 3
The number of slices for all files is 70. I was happy with that consistency, but I am worried about dim 4. I am wondering how and why I lost 30 volumes....or is this normal following the completion of BEDPOSTX?
I am using FSL 5.0.6 on OS X (10.8.2); 2.7 GHz Intel Core i5; 16 GB 1600 MHz DDR3. I used the FDT GUI.
The BEDPOSTX options I used were the following:
Fibres 2
Weight 1
Burn In 1000
Any guidance would be greatly appreciated!
Best,
Victor DelBene
