hey!!!
I know its maybe a little bit late but I've got a big problem which is like your one.
I made the same first steps. BWA is also installed, Version 0.7.4 and linked to the usr/local/bin folder bwa can be run from the command line:...
but in "tool-data" have to be some files like bwa_index.loc.sample, but there aren't!!!
And I dont know why... I could not find the reason! :////
Oops, just found it:
