主题: Re: [Genome] Create multiple alignment of 12 Drosophila species genomes
收件人: Jennifer Jackson <[email protected]>


Hello Jennifer,

There is a problem when I get the mafSpeciesSubset program.
I have already follow the guide "Source tree compilation on Debian/Ubuntu"
and the guide in *http://genome.ucsc.edu/admin/jk-install.html**.*
But there is no "mafSpeciesSubset" in the kent/src/*.
I don't know why.


Thank you very much in advance!

Shan
