Hello, We are using BioBrew in our Rocks cluster. I'm getting this very weird mistake when formatting a database with the mpiformatdb command. ----------------------------------------------------------- # mpiformatdb -N 20 -i ecoli.nt -o T -p F -n ../ecoli.nt mpiformatdb: error while loading shared libraries: libvmi20.so.0: cannot open shared object file: No such file or directory ----------------------------------------------------------- The problem is that mpiformatdb is asking to be linked with this library libvmi20.so.0 which is not part of the BioBrew rol. When I execute "#ldd mpiformatdb" I get the line "libvmi20.so.0 => not found". We have installed the ncbi toolkit 6.1.0 installed right now. What is the problem? and more importantly, what is the solution to this problem? Thank you very much for your time and help. DA
