[GRASS-dev] where are GCPs stored?

I’m trying to georectify a map.

I saved the GCPs. Now they pop up automatically and the georectifier will no longer calculate RMS error. Reloading the GCPs raises an error and the points disappear from the maps. This is a bug that needs reporting. But first, I’d like to get rid of the GCP file and try it again. But I can’t find it. It is not in the mapset AFICT, or in the .grass7 prefs folder. But it must be somewhere.

I’m on the Mac and using 7.0.2

It should be in the mapset somewhere in directory 'group'

I found it in the mapset of the map I’m georectifying from (xy location). I was looking in the mapset I was working in (my projected location).

It turns out that there is a file POINTS and POINTS.BAK. They have different formats. Reloading GCPs seems to call up POINTS.BAK. The GCPs are no longer visible on the maps when reloaded. I think you can still georectify, but you cannot modify anything or recalculate RMS errors.

I am not sure I understand what's happening. Please file a bug report with
the steps to reproduce.

I will. I am in the midst of getting a paper ready. But when I have a moment in the next few days, I’ll reproduce and report in detail. I should probably also test on 7.0.3.
