Hello, My name is olivier, I am a PhD student in biology. I have to run bioinformatical prediction on protein sequences and i chose galaxy to do it. I have some basic skills with linux, and I may have missed some steps. My galaxy server is running for more than one week now; the installation was ok, but I am facing some problems to install some dependencies: - Samtools 0.1.18 returns errors everytime I try to install it: this tool dependencys required tool dependency samtools version 0.1.18 has status error In file included from bgzf.c:32:0: bgzf.h:33:18: fatal error: zlib.h: No such file or directory #include <zlib.h> ^ compilation terminated. make[2]: *** [bgzf.o] Error 1 make[1]: *** [lib-recur] Error 1 make: *** [all-recur] Error 1 - Atlas 3.10.2 2 wont install correctly neither : mkdir: cannot create directory ATLAS/build: No such file or directory - Same goes for Numpy 1.7.1, samtools 1.2, tophat 1.4.0, rsem 1.1.17 Do you have any idea? Or tips?
