Data processing |
Galaxy platform was used for data analysis. Trimming of the reads were not due to high quality of data. The reads were mapped to the P. fragi 1793 reference genome (Gene bank accession no NQKS00000000) with the Burrows-Wheeler Aligner (version 0.7.17) using the BWA-MEM algorithm. The mapped reads, which were in BAM format, were visualised using Jbrowse genome browser (version 1.16.4) to determine the efficiency of mapping. Mapped reads were used in subsequent analyses. To estimate the number of genes overlapping with each gene in the reference genome, the SAM/BAM to count matrix of Galaxy was used. Differential expression was examined using the Voom tool (Galaxy Version 0.28) , The gene expression of P. fragi in the three stages of the biofilm: (Initiation vs Maturation), (Initiation vs Dispersal), and (Maturation vs Dispersal) were compared pairwise using the DEGUST tool (http://degust.erc.monash.edu/).
