If there is no index file, you can use SAMTools to create one (please download SAMTools from and install locally).īAM data that is aligned to an assembly can be viewed as run accessions from the SRA database. The index should be named by appending “. For viewing BAM files, an index file must be found in the same directory as the BAM file. Step 5: BAM data for SRA run accessionsīAM files can be opened from remote locations (ftp, http) and from local computers.Database of Single Nucleotide Polymorphisms (dbSNP).Database of Genomic Structural Variation (dbVar).Online Mendelian Inheritance in Man (OMIM).Database of Genotypes and Phenotypes (dbGaP).Structure (Molecular Modeling Database).Conserved Domain Search Service (CD Search).BLAST (Basic Local Alignment Search Tool).If TRUE, sends useful status messages to the console.Ĭorresponding to the input file format, that inherits from GRanges. Byĭefault, the tags "NM" and "MD" are loaded. If specified only readsĪdditional (optional) tags to load from the bam file. Default ( FALSE) is to not filter, i.e., retainĪrgument to read_bam. Provided, then it will be guessed from input file's extension.įilter rows where start/stop are invalid, and where Read_format ( file, format = detect_format ( file ), filter = FALSE, chromosomes = NULL, tags = c ( "NM", "MD" ), verbose = FALSE ) read_gtf ( file, filter = FALSE, verbose = FALSE ) read_gff ( file, filter = FALSE, verbose = FALSE ) read_bed ( file, filter = FALSE, verbose = FALSE ) read_bam ( file, filter = FALSE, chromosomes = NULL, tags = c ( "NM", "MD" ), verbose = FALSE ) supported_formats: Currently supported formats.strictly_nonunique: Return only those rows where rows per group is > 1.reduce_overlaps: Compute reduced ranges on a gtf/gff/bed/bam object.read_format: Quick and easy reading of gtf/gff/bed/bam files.non_overlaps: Generate non-overlapping intron coordinates.intersect_overlaps: Compute intersecting ranges on a gtf/gff/bed/bam object with.intersect_bed: Extract gtf coordinates intersecting input bed file.gread: Fast Reading and Processing of Common Gene Annotation and.find_overlaps: Find overlapping indices of two gtf/gff/bed/bam objects.extract: Extract features from gtf/gff objects.disjoin_overlaps: Compute disjoint ranges on a gtf/gff/bed/bam object.construct_introns: Construct introns from gtf/gff objects.as_granges: Convert data.table to GRanges object.as_data_table: Convert gtf/gff/bam/bed S4 objects to data.table and preserve.as_bam: convert 'GAlignments' object to 'data.table'.
