Tophat2 can't find Bowtie2

[rnavon]

Hi Everyone,

After my previous installed tophat/bowtie versions worked without a problem, I wanted to update to the newest versions and also installed tophat2 and bowtie2. Both programs have links to them from the /bin directory which is in the path.
When trying to run the running example, tophat2 claims I do not have the correct version of bowtie installed. I'm a UNIX newbie and would appreciate any help and ideas!

Thanks!

Can you unlink (or rename) bowtie (v.1) in /bin temporarily to see if that allows TopHat to recognize the correct version it needs?

I'll try that but it's not a permanent solution as I want to be able to keep the previous version for other users.
Can't I have both bowtie and bowtie2 installed side by side?

Just saw this over at the TopHat site. Perhaps upgrading to latest Tophat may fix your problem.

Version 2.0.8 is a quick fix release addressing the following issues:

This version correctly handles the newest version of Bowtie2 v2.1.0.
The segment mapping slow-down introduced by some Bowtie2 parameter changes in version 2.0.7 is now corrected

There is also a new version of bowtie2 (v.2.1.0) available as well.

Thanks!
It wasn't on the site a couple of hours ago. I'll install the new tophat version and see if it helps.

Updating Tophat from 2.0.7 to 2.0.8 solved the problem.
