Registration Failure #43

Closed sxg closed 6 years ago

Hi Anders,

Thanks for all the hard work put into BROCCOLI! I have an issue that's similar to one that I contacted you about a while ago. I have a time series dataset of the bowel (NIFTI and .mat). I'm registering all volumes to the last volume (vol. 35) using BROCCOLI, but the registration doesn't seem to work. The output appears to be unchanged from the input, and there are no error messages. I did the registration using FSL as well for comparison, and that worked perfectly. The issue last time was the small signal intensities I was using (10^-14 to 10^-7). This dataset ranges from 10^-9 to 10^-6, and I've tried multiplying all signals by 10^7 as well as stretching out the min and max values to adjust the contrast, but nothing seems to help. Do you mind taking a look to see what might be wrong?

Thank you! Satyam

I was able to solve the issue. Apparently my data was mis-oriented. Re-orienting the axes and rescaling my data to be within 10^-6 and 1 makes the registration work.
