Table 1.

Summary of reads from each sponge sample.

Sample	Raw reads	Post quality control	Total (paired and unpaired) reads for assembly in CLC	Total (paired) reads for trinity assembly	Contigs in CLC assembly	Contigs in trinity assembly
FL	33,220,038	33,220,038	13,723,211	7,698,642	35,219 (33%)	643 (67%)
LC	41,774,018	41,774,018	8,384,447	6,663,140
LSI	51,696,682	51,696,682	11,101,071	8,835,358

Reads were mapped to Silva 111 database prior to assembly in CLC Workbench and Trinity to remove rRNA reads, but only paired reads were used for Trinity. The percentage value shown with the number of contiguous sequences (contigs) in each assembly is the percent of reads that mapped back to the assembly.
