Adding SparseMat to MacQIIME 1.6.0

January 31, 2013

This will work only in OS 10.6 and up. To add SparseMat capabilities to your biom-format library in MacQIIME 1.6.0, please follow these instructions. This will make some OTU matrix operations work more quickly.

1. Download this file into your ~/Downloads/ folder.

2. In the Terminal, open it up and install:
cd ~/Downloads/
tar -xvf AddSparseMat2MacQIIME1.6.0_OS10.6+.tgz
cd AddSparseMat2MacQIIME1.6.0_OS10.6+

The install script will probably ask you for your administrative (sudo) password.

3. Check to make sure you're using SparseMat by default:

You will have to exit and re-initiate any open macqiime terminal subshells for the change to take effect. That second command should print the following:
