I'll investigate.
None of these are recent, right? All the recent ones should be using sloan_singleband.
Correct; last ones are from April 2015, but seem to be equally spaced throughout that time.
I haven't gotten the sloan_singleband data yet to check on those.

There were a few (13 total) sloan_singleband
classifications that also used the wrong workflow. 9 used goods_full
, 4 regular sloan
.
In general, is the subject_id unique across all surveys, or just within a survey? And how about the zooniverse_id?
subject_id and zooniverse_id should be both unique across all surveys.

Could you please give me a couple of example zooniverse_ids for sloan_singleband subjects that were classified with the wrong questions?
@willettk ?
Oops - sorry,@murraycu. Here are a couple of examples:
AGZ0007ua0 - by me (KWillett) on 2015-06-24 14:13:37 UTC
AGZ0007vxd - by an anonymous user on 2015-06-30 20:05:50 UTC

So this sloan_singleband subject had "sloan-" question IDs in its classification? http://www.galaxyzoo.org/#/examine/AGZ0007ua0
The most recent version (1.49) had some small fixes that just might help with this, though so far I can only guess at possible reasons. Maybe you can keep an eye on the more recent data. Any sloan classifications coming in now would almost certainly have to be using the new version, because only the new version (1.49) can get new subjects from the server now. Approximately 70% of users are on version 1.49 now.
There are small numbers of users with various old versions of the app installed. I guess they could be doing odd things. It would be nice if we could add a field to the classification to show the app version. At the moment we just add the same "user_agent" for all app versions.
Yes - the one above had a single annotation for a smooth galaxy (but none of the subsequent questions in the decision tree, such as what the shape of the galaxy is, anything odd, or whether they wanted to discuss it). The lack of any other annotations is another indication that there's a bug somewhere - we shouldn't record incomplete classifications like that.
"annotations" : [
{
"sloan-0" : "a-1"
},
{
"user_agent" : "murrayc.com-android-galaxyzoo"
}
],
I think the version of the "user_agent" would be a good idea to record. Is that something you can change on the app side, or is that in the database?
I can change the user_agent for each app version, adding a suffix, but then you'd have to search on the first part of the user_agent rather than the exact string. I can also easily add a user_agent_version string. Maybe @brian-c or @camallen can say what they would prefer. They were involved when we added the user_agent in issue #11 .
The lack of any other annotations
Yes, that is odd. Is this a general pattern with these bad classifications?
I've made a change that might prevent the strangeness that is happening there: https://github.com/murraycu/android-galaxyzoo/commit/1ec4d87489b1a632baa361cf54a95be6e85a72b5
Yes; pretty much all of them have just one annotation, so they aren't complete classifications.

@murraycu I think you should modify the existing user agent with a formatted suffix (and a nice delimiter to split on), e.g. Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36
I'm still not quite sure what caused this, and I can't reproduce it so far, though I have some theories which half make sense. So I've made various changes and added various checks to prevent this from happening and to prevent similarly invalid classifications from being uploaded. That's in version 1.50, which I've just released.
And the user-agent now has, for instance /1.50 at the end, so we can learn more about which app versions are doing this.
@willettk , please keep an eye on this and let me know what arrives on the server side.
Will do. Thanks, @murraycu.
I'll also be in touch shortly to discuss new groups being added to the system.

@willettk Do you still see these problems with more recent classifications, with the recent app versions (looking at the user agent)?
Super rare, but yes - happening occasionally. Example:
db.galaxy_zoo_classifications.findOne({_id:ObjectId("559049932a19957491000072")})
{
"_id" : ObjectId("559049932a19957491000072"),

"goods_full-0" : "a-1"

"user_agent" : "murrayc.com-android-galaxyzoo"
}

for a subject that should only be sloan_singleband
.
What should the date cutoff for the fix be? This is from 1 month ago.
That one has no app version suffix on the user_agent, so it must be from an older version of the app from before I added the extra checks. There can be no date cutoff because we can't force people to upgrade their app. But the user_agent tells you the app version for newer versions.
OK - so should I try again but search for an app suffix on user_agent? Can you give me an example of what that should look like?
Yes, please. The user agent for the latest version would be murrayc.com-android-galaxyzoo/1.52 , for instance.
I can confirm that there are no workflow remappings for the recent classifications that have a version number on the user agent, but that only measures agreement with other users of the app. I haven't been able to run a full check of whether every recent classification with the app uses the same workflow as everyone else who has classified the galaxy.

I assume that this is no longer a problem, but it would be nice if you checked once more and reopened this issue if necessary.
I've been looking at the data for both the
candels_2epoch
andgoods_full
subjects classified through the Android app. I'm worried that about 1 in 5 classifications seem to be using the wrong workflow; for example, there are about 500 rows that recordedcandels_2epoch
classifications for agoods_full
galaxy, and 500 that did vice versa. We've only seen this behavior in the Android app, not in the main web interface.Do you know what might be causing this?
