Hi,<br>   I am running Galaxy locally (Ubuntu 11.04) and I am getting this error message when I try to use mapping with bowtie:<br><pre>Error indexing reference sequence
/bin/sh: bowtie-build: not found
</pre>   Then I downloaded bowtie and tried to create a symbolic link using at /bin:<br> ln -s /home/koala2/bowtie bowtie<br><br>   Then I get this error message:<br>ln: creating symbolic link `bowtie&#39;: Permission denied<br>
<br>   I know that is more a linux issue than Galaxy, but does anyone have any suggestion? I changed the permission of bowtie folder and file but keep getting same error. I am logged as administrator too.<br><br>Thank you.<br>
