[GRASS-user] R: Problems in opening GCP Manager in 7.0.1RC1

No errors in terminal or or gui command console. The strange behavior seems random but surely it is not. Simply I don’t know how to replicate it.
However, since the module works well with you and no one else has reported the problem, there is surely something wrong with my procedure . Do not worry further , in the coming days I will try to go into that and if I find something new and interesting I'll let you know .
Thanks again.

Hi Anna and All,

I downloaded grass71 r65836 and repeated the rectify procedure, as follows:

1)      I imported the map to rectify in an xy Location (anzola_xy) in a Mapset named tiff.

2)      I imported the target map in a UTM Location (anzola), Mapset topografia.

3)      In the anzola Location (target Location) I clicked the Rectify button.

4)      In the Setup for georectification panel I selected the source Location and Mapset (See panel1)

5)      In the next panel (see panel2) I clicked on Create/edit group

6)      In the next panel (see panel3) I clicked  Select all and OK.

7)      In the panel I clicked Next (Successivo) (see panel 4).

8)      In the next panel (see panel 5) I clicked ‘Select target raster map to display’.

9)      In the correctly displayed map list I choosed the topo15030u4 map  as target map (see panel 6).

10)   The map name was inserted in the panel (see panel 7) but when I clicked Fine (The Finish button) the ‘Manage Ground Control Points’ window was not displayed and the module seemed to be closed.
Wath is curious is that sometime, when I click ‘Select target raster map to display’ the maps of the source Location (not the target) are displayed (see panel8) and the selection of one of the maps allows the opening of the ‘Manage Ground Control Points’ window (but with the wrong map in the target window, of course) (see panel9)
The same procedure works well with winGRASS6.4.4 and with GRASS7.0.1RC1 on ubuntu.

I can see the problem from the screenshots, but I can't replicate it. You are saying the main GCP window was not displayed - was there any kind of error in terminal or gui command console? And when you say it happens sometimes, does it mean it behaves randomly? (it shouldn't behave randomly)

Thanks for your interest

I’m having some problem in using the GCP Manager in 7.0 for Windows. In the panel for the selection of the raster target to display, the source Location and Mapset are listed and there is no way to select a map from the target Location and Mapset.


I fixed one problem just now in r65839, so you can try it out with a new winGRASS build [1] when ready. But I am not sure if that fixes the problem you have - did you get any error message in the GUI command console? The problem is in the wizard or after the GCP application opens?

No problems in 6.4.4.
Is this a bug?
Thanks in advance
