[GRASS-user] ValueError: too many values to unpack

GRASS GRASS user

Hi,

I have installed the latest version of GRASS 7 (updated as on Jan 12,
2013) from here http://grass.osgeo.org/grass70/source/snapshot/ on my
ubuntu 11.04.

while running the t.rast.mapcalc I am getting following error message:

Start temporal sampling
100%
Start mapcalc computation
Traceback (most recent call last):
  File "/home/manish/src/dist.x86_64-unknown-linux-gnu/scripts/t.rast.mapcalc",
line 102, in <module>
    main()
  File "/home/manish/src/dist.x86_64-unknown-linux-gnu/scripts/t.rast.mapcalc",
line 97, in main
    base, method, nprocs, register_null, spatial)
  File "/home/manish/src/dist.x86_64-unknown-linux-gnu/etc/python/grass/temporal/mapcalc.py",
line 250, in dataset_mapcalculator
    start, end = sample_map_list[i].get_relative_time()
ValueError: too many values to unpack

Any help to resolve this issue?

Hi Manish,
This error was solved recently (13.01.2013) [1] . Unfortunately is the current snapshot to old for this changes. Soon a more recent snapshot should be available.

Best regards
