Fig. 1

Schematic overview of the IMP pipeline. Cylinders represent input and output while rectangles represent processes. Arrows indicate the flow between input, processes, and output. MG — Metagenomic data, MT — Metatranscriptomic data, rRNA — ribosomal RNA, NLDR-GS — genomic signature non-linear dimensionality reduction. Processes, input, and output specific to MG and MT data are labeled in blue and red, respectively. Processes and output that involve usage of both MG and MT data are represented in purple. A detailed illustration of the “iterative co-assembly” is available in Additional file 1: Figure S1
