Hi,
I am having trouble with multiple input in pyGRASS:
Example:
-------------
b_in=[b1,b2,b3,b4,b5,b7]
i.albedo(input=b_in, output=b_albedo, flags="lc", overwrite=OVR)
input has a multiple raster band names requirement (6 here),
using a list to define b_in does not work.
What kind of container should I use?
thank you

you should use a list as you do...
I don't have your map so I'm not able to reproduce the problem on my
machine...
I've try with:
{{{
from grass.pygrass.modules.shortcuts import imagery as i
alb = i.albedo
alb(input=['b1', 'b2', 'b3', 'b4', 'b5', 'b7'],
output='b_albedo', flags="lc", overwrite=True, run_=False)
alb.get_bash()
}}}
and return 'i.albedo input=b1,b2,b3,b4,b5,b7 output=b_albedo -l -c --o'
that it seems correct to me...
Can you provide some more details about "b_in does not work"? 
What kind of error do you have?
Best regards
Pietro
ps: thank you for testing!
Hi Pietro,
here is the summary of what I want to do...
OVR=True
pref='LE71340442011084PFS00_B'
b1=pref[:-2]+".surf.1"
b2=pref[:-2]+".surf.2"
b3=pref[:-2]+".surf.3"
b4=pref[:-2]+".surf.4"
b5=pref[:-2]+".surf.5"
b7=pref[:-2]+".surf.7"
b_in=[b1,b2,b3,b4,b5,b7]
b_albedo=pref[:-2]+".surf.albedo"
print "Albedo:\t",b_albedo
i.albedo(input=b_in, output=b_albedo, flags="lc", overwrite=OVR)
r.colors(map=b_albedo,color='grey')
Ciao,
Yann

i.albedo flag "-c" is generating a segfault on this, not anything to
do with pyGRASS
