Quick start

# Browse the hg38 human genome. Internet connection required.
tgv

• Quit: :q
• Movement:
  • Left / down / up / right: h/j/k/l:
  • Faster left / right: y/p
  • Next gene / previous gene / next exon / previous exon: W/B/w/b
  • Repeat movements: _number_ + _movement_ (e.g. 20B: left by 20 genes)
• Zoom in / out: z/o
• Go to gene: :_gene_ (e.g. :TP53)
• Go to a chromosome position: :_chr_:_position_: (e.g. :1:2345)

View alignments

# View BAM file aligned to the hg19 human reference genome
tgv sorted.bam -g hg19

# Start at a coordinate
tgv sorted.bam -r 12:25398142 -g hg19

# View a indexed remote BAM, starting at TP53, using the hg38 reference genome
tgv s3://my-bucket/sorted.bam -r TP53

# Use --no-reference for non-human alignments
# (Sequence / feature display not supported yet)
tgv non_human.bam -r 1:123 --no-reference

FAQ

• How to quit TGV?
  Just like vim :) Press Esc to ensure you're in normal mode, then type :q and press Enter.

• Where are the reference genome data from?

  • Sequences: UCSC Genome Browser API
  • Annotation: UCSC MariaDB, hg19 / hg38, table ncbiRefSeqSelect (same as IGV)
