I’m trying to analyze my post-picrust data to find differences between conditions in our samples, and it seems like STAMP is the right tool to use - except I’m having a heck of a time getting it installed. I’ve tried conda installs on Mac and linux and I keep running into problems (e.g. pyqt4 not found). Is there a better way?

Hi malwolficus,

Thank you for reaching out to bioBakery Lab and apologies for taking long to get back to you.

It looks like STAMP requires an additional dependency pyqt4. Please try going to the link here ([https://riverbankcomputing.com/software/pyqt/download](https://riverbankcomputing.com/software/pyqt/download)) and installing the right package of pyqt4.

Additionally, please take a look at [Maaslin2](http://huttenhower.sph.harvard.edu/maaslin2) and [Lefse](https://huttenhower.sph.harvard.edu/lefse) for analyzing the post picrust data.

Thanks,  
Sagun Maharjan
