Fix mddatasrc for all studyforrest datasets #62

adswa · 2023-04-13T15:13:06Z

At the moment, the Studyforrest datasets hosted here on GitHub are all broken. The reason for this is a faulty special remote mddatasrc pointing to psydata.ovgu.de, which used to redirect to datapub.fz-juelich.de (where the data was migrated to), but was taken down recently. The first user issue that brought this problem to light is psychoinformatics-de/studyforrest-data-visualrois#6.

Although I've only probed a handful of repositories/subdatasets in this repo, I believe they all have a now broken mddatasrc special remote registered. I suggest we put in a coordinated effort to fixing this with as many people as possible. @bpoldrack outlined a fix for this issue in psychoinformatics-de/studyforrest-data-visualrois#6. Here's my translation for the general procedure that anyone can follow:

Take a repo from the list below, tick if off so that others don't duplicate efforts, and clone it from GitHub.
Check if you see errors about mddatasrc during cloning. If not, nevertheless try to retrieve data to make sure it all works. If everything works, move to the next dataset; if not, move to 3.
As a first sanity check, investigate remote.log and make sure there is only one mddatasrc special remote (git cat-file -p git-annex:remote.log is the command to do it). If there are two, leave a note, and move to the next dataset for now.
Make a note of the UUID of the mddatasrc special remote in remote.log
Go to https://datapub.fz-juelich.de/studyforrest/studyforrest/ and find the folder that corresponds to the dataset you're handling. The names aren't always identical, but should be easily inferable. If unsure, compare directory contents and filenames. If you can't find a corresponding directory, ask for help in the chat. Make a note of the URL (e.g., https://datapub.fz-juelich.de/studyforrest/studyforrest/aligned) and append /.git
In the cloned dataset, remove the git remote mddatasrc using git remote remove mddatasrc
Fix the special remote mddatasrc using its UUID as an identifier, and the URL you constructed from datapub.fz-juelich.de (see example below) to fix the location information:

git annex enableremote 7dd5970d-cee5-404e-a3be-6430ec03657f   location=https://datapub.fz-juelich.de/studyforrest/studyforrest/aligned/.git

Retrieve a file using datalad get to confirm that this fix worked, and retrieval from mddatasrc is possible again
The fix caused an update in the git-annex branch. datalad push the changes back to GitHub. There is no need (or possibility) to do a pull request. Make sure that the git-annex branch gets successfully pushed. If you run into permission errors, seek help in the chat.
After pushing, re-clone the repo, and retry data retrieval. If things don't work, add a comment to this issue and seek help.

christian-monch · 2023-04-13T19:05:54Z

Thanks @adswa for the great instructions!

I have changed the mddatasrc location in https://github.com/psychoinformatics-de/studyforrest-data-phase2, and datalad get works now.

I get the same [INFO]-message about an unavailable RIA store, which I assume is OK, right?

adswa · 2023-04-13T19:45:45Z

Yes, this message is unrelated to the special remote 👍

adswa · 2023-04-14T09:00:20Z

Thx! In this case, the remote is not called mddatasrc but psydata - can you replace all comments with mddatasrc with psydata? I believe this should do the trick. Thank you so much! :)

https://github.com/psychoinformatics-de/studyforrest-data-templatetransforms (fixed, but some get "impossible" and "errors" remain. See datalad get sub-01)

I'm investigating 👍

Thx, I will investigate and report back what I found! 👍

adswa · 2023-04-14T09:31:17Z

Edit: This was fixed and pushed. Done!

First observation about https://github.com/psychoinformatics-de/studyforrest-data-aggregate: Some files on datapub.fz-juelich.de seem access-restricted. I don't know what to do here, so I'll tag @aqw and @mih for potential insights

Edit: I only now realized that this were all annexed files in the dataset, the rest is in Git

adswa · 2023-04-14T09:40:30Z

EDIT: The problem is that the dataset on https://datapub.fz-juelich.de/studyforrest/studyforrest/templatetransforms/.git/ contains an old version, with the last commit from 2016. The dataset on GitHub has more recent commits. They seem to originate from juseless, but other than the commits, these changes were not published. If we push this dataset from data1:/data/project/studyforrest/superds/derivative/image_space_transformations to datapub, this should get fixed. I don't have permissions to do this.

For https://github.com/psychoinformatics-de/studyforrest-data-templatetransforms I also need some help, so I'm tagging @mih and @bpoldrack:

There are files that can't be retrieved, e.g.,
sub-01/bold3Tp2/in_t1w/brain.nii.gz
sub-01/bold3Tp2/in_t1w/xfm_6dof.mat
sub-01/t1w/in_bold3Tp2/brain.nii.gz
sub-01/t1w/in_bold3Tp2/xfm_6dof.mat

This is the availability information registered for those files (exemplary for one, matches all of them) - the important bit is that the enabled [mddatasrc] special remote isn't listed.

❱ git annex whereis sub-01/bold3Tp2/in_t1w/xfm_6dof.mat
whereis sub-01/bold3Tp2/in_t1w/xfm_6dof.mat (4 copies) 
  	43613943-720c-4018-a7a5-40c6fb9ad603 -- inm7-storage
   	529fccea-fdf5-4266-99a4-769e2638f82f -- mih@medusa:/home/data/psyinf/forrest_gump/collection/tnt

   	f2ec3af6-e466-4951-b1dc-4991ade8f171 -- mih@data1:/data/project/studyforrest/superds/derivative/image_space_transformations
ok

However, the files are available at mddatasrc, for example https://datapub.fz-juelich.de/studyforrest/studyforrest/templatetransforms/sub-01/bold3Tp2/in_t1w.

I already did an git annex fsck --from mddatasrc which reported success, but did not update availability. My question is: how can I tell git-annex that for those files in question mddatasrc is a suitable location, too? Is it a job for addurls?

A side question is whether those files are left unregistered on purpose, e.g., because of data privacy.

adswa · 2023-04-14T09:50:29Z

As for https://github.com/psychoinformatics-de/studyforrest-data-phase2-denoised , we don't have this data, all sources are with OpenNeuro as far as I can see.

Edit: The dataset here on github is outdated. The problem is that the data was updated upstream, and the content from the now unavailable files was moved to *_decomposition.json in commit de145f67a3da26f1d39187403340d7380d928cf2 tag 1.3.0. ~~I will get the dataset in sync with the one from OpenNeuro~~ After a quick discussion in the chat, we decided to add a fork to the OpenNeuro Dataset instead of synching.

A quick overview of a TODO for @mih:

Please go to data1:/data/project/studyforrest/superds/derivative/image_space_transformations (I hope this still exists)
Check the git history of the dataset. The last commit registered at mddatasrc is 424d152. Here's the log of what happened in the mean time on GitHub (psychoinformatics-de/studyforrest-data-templatetransforms@424d125 is at the bottom):

bpoldrack · 2023-04-14T11:33:44Z

@adswa

I already did an git annex fsck --from mddatasrc which reported success, but did not update availability.

That is strange. It should update availability if there was a change and it would be the way to go.
When you say "reported success", do you mean a zero exit of the command or that it reported to find those files via special remote?

adswa · 2023-04-14T11:40:04Z

See my edit in that post, and most recent comment to @mih with a fix, @bpoldrack: The files in question differ in version between GitHub and datapub.
Datapub is outdated. It does not know the updated annex keys that GitHub knows about (but doesn't carry). So while a file on GitHub points to annex/objects/zW/..., datapub does not have this in its object tree yet (because this version of the file wasn't pushed to it yet, it only lives on data1). I figured this when I tried to run git annex setpresentkey to manually add the mddatasrc to the key.

adswa · 2023-04-14T11:46:06Z

Another TODO for @mih:

Please remove https://github.com/psychoinformatics-de/studyforrest-data-phase2-denoised

I lack the permissions to do so, and this dataset is superfluous as I have forked the openneuro dataset as discussed in the chat as a maintained alternative to https://github.com/psychoinformatics-de/studyforrest-data-phase2-denoised_openneuro

TODO for me:

~~[ ] register alternative dataset in studyforrest-data superdataset~~ The dataset wasn't a subdataset of studyforrest-data it seems
