FR-HIT in pipeline

PMCID: 3170331
PMID: 21931709
DOI: 10.1371/journal.pone.0024417

[…] for principal coordinates analysis (pcoa)., several quality control filters were applied to wgs raw reads before analysis. first, host contaminants (sequences of bovine origin) were removed using fr-hit against the bovine genome btau 4.0 (cutoff: 95% identity over 95% of the entire sequence length). the possible artifacts (redundant reads) were then identified and excluded using cd-hit .

[…] sequences available for these bgps (metagenome accession nos. at the ncbi database: sra357208-09, sra357211, sra357213-14, sra357221-23) were mapped on the genome sequences of these isolates with fr-hit (v0.7; []) to sensitively recruit also metagenomic reads with lower sequence identity (global alignment down to 75% nucleotide sequence identity; additional file )., as a baseline to compare […]

[…] of n. mobilis or nitrococcus-like phylotypes., selected osd metagenomes, tara, and mg-rast samples were mapped to the n. mobilis nb-231 genome (accession no. gi|211606481|ref|nz_ch672427.1) using fr-hit version 0.7 with the following parameters: -e 0.001 -u 0 -p 8 -c 80 -m (dynamically set to 40% of average read length in a sample). hits for nitrogen and sulfur cycling genes of interest […]

[…] raw reads from the u1362a metagenome were mapped to the six scaffolds that make up the “ca. d. cowenii” genome bin and the “ca. d. audaxviator” genome. recruitment was performed using fr-hit v0.7.1 () with default parameters (minimum sequence similarity 75%) and reporting a single best top hit for each read (-r 1)., full length ssu rrna genes from the raw quality-filtered u1362a […]

[…] genomes as described recently []. therefore, the combined metagenome sequencing dataset (see above) was used, representing the thermophilic biogas-producing microbial community. afterwards, the fr-hit software tool [] was used to perform a global alignment against the completely sequenced genomes of the strains described above. an identity cutoff of 75 % was used to align the sequencing […]

[…] proteins assigned to sar324 cluster bacteria were subjected to the following annotation analyses. relative abundance of the binned sar324 was estimated by read recruitment using bowtie2 and fr-hit. the reads were recruited to the three assembled metagomes as well as to the four binned sar324 genomes. the abundance was derived from the percentage of successfully recruited reads […]
