BACKGROUND: Multiple RNA samples are frequently processed together and often
mixed before multiplex sequencing in the same sequencing run. While different
samples can be separated post sequencing using sample barcodes, the possibility
of cross contamination between biological samples from different species that
have been processed or sequenced in parallel has the potential to be extremely
deleterious for downstream analyses. RESULTS: We present CroCo, a software
package for identifying and removing such cross contaminants from assembled
transcriptomes. Using multiple, recently published sequence datasets, we show
that cross contamination is consistently present at varying levels in real data.
Using real and simulated data, we demonstrate that CroCo detects contaminants
efficiently and correctly. Using a real example from a molecular phylogenetic
dataset, we show that contaminants, if not eliminated, can have a decisive,
deleterious impact on downstream comparative analyses. CONCLUSIONS: Cross
contamination is pervasive in new and published datasets and, if undetected, can
have serious deleterious effects on downstream analyses. CroCo is a
database-independent, multi-platform tool, designed for ease of use, that
efficiently and accurately detects and removes cross contamination in assembled
transcriptomes to avoid these problems. We suggest that the use of CroCo should
become a standard cleaning step when processing multiple samples for
transcriptome sequencing.
