Hey, 1 I installed Galaxy locally. 2 I also have BWA installed and then used the 3 shed repository to get the bwa wrapper. 4 I have the reference genome now I'm stuck with the calculate SA coordinate. Segmenation fault. Google tells me that it could be a problem with -space (I have 4GB left) -the version I use. (I use 0.5.9 and did a succesful alignment with 0.7.5a, but the tool shed says 0.5.9, hence *could I just change to the current version* (without Galaxy knowing it), with which I did a succesful alignment?)
