Sorry, there is holiday.
I import the raster. Then set the region. This is my syntax :
g.region -up raster=rgb.1
The "-u" flag does not set the current computational region to your
raster. It just reports what would happen if you do reset the region.
Please try:
g.region -ap rast=rgb.1
and report back the output.
projection: 3 (Latitude-Longitude)
zone: 0
datum: wgs84
ellipsoid: wgs84
north: 13:07:42.9N
south: 27:38:15.5S
west: 100:55:15.7E
east: 131:15:38.1E
nsres: 0:00:36.8
ewres: 0:00:36.8
rows: 3988
cols: 2968
cells: 11836384
(Sat Dec 26 05:24:05 2020) Command finished (0 sec)
Then, from menu Imagery > Classify image > Interactive input for
supervised classification. Then the output is like this :
G__open(read): Unable to open '/home/mega/newLocation/PERMAN
ENT/.tmp/mega/vector/trAreas114130/frmt': No such file or
directory
I don't know why there is that message.
Then in Plots Menu, I choose Scatter Plots. I click Add scatter plot.
In the Name of imagery group, I choose the raster. In the Name of
imagery subgroup, I type the name. I click Create/edit group. In x and
y axis, I choose a band. I click Add. Then there is a message that :
"Scatter plot cannot be added.
Multiple of bands ranges <x53.1@PERMANENT:65529 *
x53.1@PERMANENT:65529 = 4294049841 > is higher than maximum limit
<16810000> "
In this case, I have defined the region. Thank you for your attention.

Please post your computation region (i.e. the output of g.region
-p) and
the command you used.
