Unable to ingest nifti

[vikramc1]

After copying & pasting the "putnifti.py" file to my working directory, I ran:

python putnifti.py '52.91.173.4/nd' 'FA_Maps' 'dti' 'KKI2009_113_1_DTI_aligned.nii'

The resulting url was printed as: http://52.91.173.4/nd/ca/FA_Maps/dti/nii/

The resulting error was: Failed http://52.91.173.4/nd/ocp/ca/FA_Maps/dti/nii/. Exception HTTP Error 502: Bad Gateway.

@vikramc1 @gkiar Use mri.neurodata.io. Let me know if there is an issue.

attempted to create a channel for my project on mri.neurodata.io and got the following error:

Failed to create channel. (1049, "Unknown database 'kki2009'")

EDIT:

I accidentally chose the 'Link to existing database' option when creating the project. Problem fixed.

[vikramc1]

Still having some issues ingesting.

Command I typed: python putnifti.py 'mri.neurodata.io/nd' 'kki2009' 'dti' 'dti/KKI2009_113_1_DTI_aligned.nii.gz'

First argument: baseurl
Second argument: token
Third argument: channel
Fourth argument: filename

(putnifti.py taken from here)

URL generated: http://mri.neurodata.io/nd/ca/kki2009/dti/nii/
Error encountered: Failed http://mri.neurodata.io/nd/ca/kki2009/dti/nii/. Exception HTTP Error 502: Bad Gateway.

Additional Information:

• Dataset, Project, Channel, Token all made public/various combinations of private/public and still same error
• Tried baseurl = mri.neurodata.io and got Failed http://mri.neurodata.io/ca/kki2009/dti/nii/. Exception <urlopen error [Errno 32] Broken pipe>.

@vikramc1 Should be resolved now. Try again. It will take some time for it to finish. I would run it in a screen/tmux.

[jovo]

thanks @kunallillaney

[vikramc1]

Still not working but with a different error.

@kunallillaney perhaps you can provide an example of this working?

@vikramc1 Just a sanity check. Are you actually typing single quotation marks in your command line arguments?

[vikramc1]

Yes I am

[kunallillaney]

@vikramc1 Why are you doing that, because they are strings? When you pass command-line arguments to a python script you do not do that.

Here is the command to run.
python putnifti.py mri.neurodata.io/nd kki2009 dti dti/KKI2009_113_1_DTI_aligned.nii.gz

Do ensure here that the path to the file is correct from the point where you run your script.

[vikramc1]

@kunallillaney I tried that and got the same error: Failed http://mri.neurodata.io/nd/ca/kki2009/dti/nii/. Exception HTTP Error 504: Gateway Timeout.

[kunallillaney]

@vikramc1 I messaged you on slack. Also, I posted the same file via my computer and it worked. So I am not sure what you are doing wrong(Maybe the file path is wrong). This can be easily verified in person. :)

[kunallillaney]

@vikramc1 I have identified the issue but there is no easy fix for it as of now.
@randalburns @perlman The NGINX web-server is timing out after 10mins(we have set the UWSGI read timeout to 600secs) because the job takes longer then that. I can increase this number arbitrarily but that will lead to security issues.

[kunallillaney]

@vikramc1 Were you able to get all the data in? The timeout fix can hopefully work in the short-term. Also let me know if you can view the data . I sent you a sample URL and XY doc link over slack.
