bc_summarize - Summarize community composition
bc_summarize -input_files my_communities.generic \ -output_prefix my_converted_communities
This script reads a file containing biological communities and summarizes it. In practice, this means transforming community member counts into relative abundance (taking into account any weights that members could have) and merging members that have the same lineage. Other popular practices include grouping members with a low abundance together into an 'Other' group and representing the taxonomy at a higher level, such as phylum level instead of specied level. See Bio::Community::Tools::Summarizer for more information.
Input file containing the communities to summarize. When providing communities in a format that supports only one community per file (e.g. gaas), you can provide multiple input files.
Tab-delimited files containing weights to assign to the community members.
When using a files of weights, define what to do for community members whose weight is not specified in the weight file (default: weight_assign.default):
* $num : assign to the member the arbitrary weight $num provided
* file_average : assign to the member the average weight in this file.
* community_average : assign to the member the average weight in this community.
* ancestor: go up the taxonomic lineage of the member and assign to it the weight of the first ancestor that has a weight in the weights file. Fall back to the 'community_average' method if no taxonomic information is available for this member (for example a member with no BLAST hit).
See the weight_assign() method in Bio::Community::IO for more details.
Path and prefix for the output files. Default: output_prefix.default
Convert counts into relative abundances (in percentage, taking into account weights): 1 (yes), 0 (no). Default: convert_relab.default
Merge community members with the exact same lineage. Default: merge_dups.default
By default, the lineage of species has to match character for character for them to be considered duplicates. When you activate this option (1:on, 0:off), their lineage is parsed and interpreted taxonomically. For example, these three members would be duplicates:
k__Bacteria; p__Proteobacteria; c__Alphaproteobacteria k__Bacteria;p__Proteobacteria;c__Alphaproteobacteria k__Bacteria;p__Proteobacteria;c__Alphaproteobacteria;o__;f__;g__;s__
Group community members with a relative abundance less than the specified threshold (in %) in ALL the communities into an 'Other' group. Default: relab_lt.default %
Group members belonging to the same taxonomic level. For the Greengenes taxonomy, level 1 represents kingdom, level 2 represents phylum, and so on, until level 7, representing the species level. Members without taxonomic information are grouped together in a member with the description 'Unknown taxonomy'. Default: none
