comment Cropping or removing borders (not NoData) from multiple scanned and georeferenced maps (ArcMap or QGIS)
First try to see what is the value of the black edge with the identifying tool. Then you can try to covert your file to another/same format and definig the null value and keeping the files in the same crs (raster/conversion/translate(convert format))

I also think that gene´s comments qualify as an answer. Following the link it clarifies the issues.

comment How to clip a lines vector layer to a polygon layer in QGIS?
why not trying to clip the raster file? take in to account that both layer must be in the same crs also.

comment Scale and Z factor have no effect on hillshade analysis in QGIS
When you are using a DEM with latlon coordinates in decimal degrees and vertical units in meters you have to set the scale (ratio of vertical units to horizontal units) to 111120. I tried with a couple of DEMs from Aster I have not a problem. This setting aplies not only to hillshading but also for slope calculations. Hope it helps

comment Missing Georeferencer
Thanks, I was used to see it without activating it in manage and install plugins. Now there is a little glitch, since after I invoke the georeferencer, the georeferencer appears, do not respond for a little moment and I have an error stating "bad allocation". After that i can play with the georeferencer.

I do not know what version of Qgis you are running. I use 2.01 64 under win 7. R. drain gives me a big blag raster. The path is there but I can not see it. The way I handle the problem was to conver th r.drain raster to vecto with r.to.vect.line. Then the path is visible.

I run r.cost with the native resolution of your dem and I have no problem, bear in mind that I am using qgis 2.01 64 in win7 with an I7 and 16gb of ram, so it was fast (les than a minute)

Hello,sorry for the delay, I was able to run rwalk,and rdrain with the model you mentioned. The only thing I changed was the raster resolution. As I understand when you defined your region , the raster resolution is set to 1 (in this case 1 meter). So look for an icon that tells "grass region settings" and change the resolution to something esle more than one. Your dem is 5, so try with 5 or 10. Hope it helps
