[GRASS-user] r.li.setup

Dear List,
I've been trying to use the r.li suite in a landscape ecology course and found the r.li.setup fails to create configuration files if one tries to setup the sampling frame by drawing regions or by using vector layers. The moving window, however, works. Any suggestions on how to overcome this?
Thanks,
Ravi

Config file for region (2 regions were attempted but the input dialoge did not allow me to digitise the regions of interest.)
SAMPLINGFRAME 0|0|1|1
MASKEDSAMPLEAREA 0.0|0.0|1.0|1.0|one
MASKEDSAMPLEAREA 0.0|0.0|1.0|1.0|two
MASKEDSAMPLEAREA 0.0|0.0|1.0|1.0|one
MASKEDSAMPLEAREA 0.0|0.0|1.0|1.0|two

Config file for vector input (vector comprised of 6 polygons)
SAMPLINGFRAME 0|0|1|1
