no v.1.30 for Linux 32-bit?

I downloaded Linux executable 32-bit from the download page,
tried it out, and it says “mothur v.1.22.2 Last updated: 11/7/2011” on the top of the screen.

Is there not yet a v.1.30 for Linux?

I just double checked and the version on the wiki is 1.30.2. How are you starting mothur? Could you have an older version of mothur installed somewhere in your path? Can you try the following:

  1. Open a command prompt
  2. cd into the 1.30.2 mothur directory
  3. Run ./mothur
