Hi, I've run blastclust on a set of my own sequences and I would like to know how to interpret the results in the hits file. Is this file not supposed to be readable as a plain text file, or have I done something wrong? If not, is there a way to read the contents of the file (any programs that can interpret the file into human readable format)? I am currently running this under Linux, although I would also like to know how to run blastclust under Windows. Everytime I try to run it under Windows I get an error message saying that blastclust has encountered a problem and needs to close. Has anyone used blastclust under Windows before and know what could be causing it to crash? I've tried creating both a .ncbirc file in the blast bin directory and a ncbi.ini file under WINDOWS. I appreciate your help with either of these problems. Regards, Joanna
