  • mrifilt3, mricrop, mrisubset, and possibly others mangle the parameters file. In particular, if you operate on a DWI, the output won't have the b matrix recorded. Also the MRISpaceShift just gets clobbered to 0 0 0.
    • A workaround right now for the b matrix, TR, and TE is 
      grep "^b\|e0" $src/parameters >> $dest/parameters
  • Streamtube generation gets slower and slower as the program runs. What's going on? Is it running out of memory, reading inefficiently through a big file, doing something probabilistic that gets less likely the more tubes there are? We need a speedup!
  • Most operations, including tensor fitting and tube generation, are highly parallelizable. It'd be great if we could throw them on the department's compute grid.
