| Data processing |
Sequencing reads were processed and mapped to the respective reference sequences using the BLASR mapper (http://www.pacbiodevnet.com/SMRT-Analysis/Algorithms/BLASR) and the Pacific Biosciences' SMRT Analysis pipeline (http://www.pacbiodevnet.com/SMRT-Analysis/Software/SMRT-Pipe) using the standard mapping protocol.
To identify modified positions, we used Pacific Biosciences' SMRTPortal analysis platform, v. 2.0.1, which uses an in silico kinetic reference, and a t-test based kinetic score detection of modified base positions (details are available at http://www.pacb.com/pdf/TN_Detecting_DNA_Base_Modifications.pdf)
Modified sites were grouped into motifs using MotifFinder (v1)2.
Genome_build: As indicated by IMG genome ID in the individual samples section (http://img.jgi.doe.gov/home.html)
Supplementary_files_format_and_content: modifications.gff files are comma separated text files that contain data for genome positions with Qmod scores greater than 20; Data includes Qmod scores, IPD ratios, coverage, and sequence contexts for a +/- 20 nt window surrounding the modified position (see https://github.com/PacificBiosciences/Bioinformatics-Training/wiki/Methylome-Analysis-Technical-Note for more details)
Supplementary_files_format_and_content: modifications.csv files are comma separated text files that contain data for all positions (both strands) in the reference sequence; data includes Qmod score, IPD ratio, and coverage. (see https://github.com/PacificBiosciences/Bioinformatics-Training/wiki/Methylome-Analysis-Technical-Note for more details)
Supplementary_files_format_and_content: motif_summary.csv files contain the genome-wide summary of the methyltransferase recognition motifs discovered in this sample. (see https://github.com/PacificBiosciences/Bioinformatics-Training/wiki/Methylome-Analysis-Technical-Note for more details).
Supplementary_files_format_and_content: motifs.gff files are similar to the modifications.gff files. These files contain information about all sites detected as modified, all locations of a discovered motif (including those which are apparently unmodified), and also the overlap between the modifications and motifs. (see https://github.com/PacificBiosciences/Bioinformatics-Training/wiki/Methylome-Analysis-Technical-Note for more details).
