EMP Biom Files Pt. III

Got in touch with Sean Gibbons and he was able to forward some code:
https://github.com/klocey/rare-bio/blob/master/tools/ConvertBiom/ConvertBiom.py
***script scans through giant biom file in smaller pieces, rather than loading entire file into memory

Output is a sparse abundance matrix
each row is: OTU, site, number of reads

Example (first 10 lines from open reference biom file):
0 0 7.0
0 1 10.0
0 2 13.0
0 3 7.0
0 4 2.0
0 5 3.0
0 6 3.0
0 7 3.0
0 158 320.0
0 159 32.0

Not really sure how to interpret data
