Hi Developers,

I was trying to register between two stacks with the following commands:

cmtk  make_initial_affine --centers-of-mass "refbrain/RFP_temp.nrrd" "images/B1ZDunsharp.nrrd" "Registration/affine/aff_init.xform"

cmtk registration -v --mi --initial "Registration/affine/aff_init.xform" --auto-multi-levels 4 --match-histograms --dofs 6,12 -o "Registration/affine/affRFPB1ZD.xform" "refbrain/RFP_temp.nrrd" "images/B1ZDunsharp.nrrd"

cmtk warp -v -o "Registration/warp/warpRFPB1ZD.xform" --grid-spacing 2 --refine 6 --jacobian-weight 0.05 --rigidity-weight 0.1 --exploration 0.05 --accuracy 0.001 --match-histograms --exact-spacing --mi --output-intermediate --initial "Registration/affine/affRFPB1ZD.xform" "refbrain/RFP_temp.nrrd" "images/B1ZDunsharp.nrrd"

Then I tried to apply the registration to the original stack by:

cmtk reformatx -v -o reformB1ZD_warp.nrrd --floating images/B1ZDunsharp.nrrd refbrain/RFP_temp.nrrd Registration/warp/warpRFPB1ZD.xform


However, the reformatx never worked. It always gives the error message
"The file/directory Registration/warp/warpRFPB1ZD.xform does not seem to be in a supported transformation format"

Do you have any suggestions what could lead to the problem? Thanks!

Best.
Dan

Hi Dan -

Sorry for the delay in responding.

I don't see anything obviously wrong with your command lines, so rather than guessing, would you mind uploading the transformation some place so I can take a look?

Also, in the same context (same working dir etc) as the reformatx command, what does output "ls -l Registration/warp/warpRFPB1ZD.xform" produce?

Thanks!
Torsten

Hi Torsten,

Sorry for my delayed reply. I ran several tests (using munger script instead, not the commands that I posted earlier here) with different data sets and here is my finding: for outputs that are readable in reformatx, the output folder contains files like:

cmd.sh level-01.list level-03.list level-05.list settings studylist
level-00.list level-02.list level-04.list registration.gz statistics

While for those unreadable in reformatx, the "registration.gz" is missiing. Sometimes even everything is missing except "cmd.sh".  I was wondering what makes this happen.  I have double checked all my data format and units to make sure that they are consistent.

Hi Dan -

If the "registration.gz" file is missing, then there is no transformation stored in your output directory, which would certainly explain why you cannot read it.

So really, the question is, why the files aren't written sometimes. I assume you're not out of disk space? (Sorry, I have to ask)

The only reason I can think of why the registration.gz file isn't written is that the tool that produces it (warpx?) crashes either during registration or during file writing. Do you have any outputs logged from the commands that produces incomplete outputs?

Best,
  Torsten

Hi Torsten, 

I am for sure not running out of disk space, so I guess the registration step got crashed.  One trial that failed to proceed to warping gives this logged output:

[color=#0000ff]I did not see any error message here, so I am very confused. [/color]

[color=#0000ff]Thanks for looking into my problems. Happy Holidays!

Hm. There doesn't seem to be anything obviously wrong here.

Another question would be, do the same cases consistently fail and succeed, respectively? That is, if you re-run a failed run with exactly the same command, would it (sometimes) then succeed?
