NAME

samtools-tview - display alignments in a curses-based interactive viewer.

SYNOPSIS

samtools tview [-p chr:pos] [-s STR] [-d display] in.sorted.bam [ref.fasta]

DESCRIPTION

Text alignment viewer (based on the ncurses library). In the viewer, press ‘?’ for help and press ‘g’ to check the alignment start from a region in the format like ‘chr10:10,000,000’ or ‘=10,000,000’ when viewing the same reference sequence.

OPTIONS

-d display

Output as (H)tml, (C)urses or (T)ext.

The width of generated text is controlled by the COLUMNS environment variable. Note this may be a local shell variable so it may need exporting first or specifying on the command line prior to the command. For example

export COLUMNS ; samtools tview -d T -p 1:234567 in.bam

	-p chr:pos		Go directly to this position
	-s STR		Display only alignments from this sample or read group
	-X		If this option is set, it will allows user to specify customized index file location(s) if the data folder does not contain any index file. Example usage: samtools tview [options] -X </data_folder/data.bam> [/index_folder/index.bai] [ref.fasta]
