Sam’s Notebook:Software Installation – RepeatMasker v4.0.7 on Emu/Roadrunner Continued


After yesterday’s difficulties getting RMblast to compile, I deleted the folder and went through the build process again.

This time it worked, but it did not put rmblastn in the specified location (/home/shared/rmblast).
