Grok your data
The objective of bioSyntax is to bring you closer to your data, giving you an intuitive & empathetic understanding of biology. To appreciate all that bioSyntax has to offer read this short manual (~10 minutes) and go explore.

bioSyntax integreates seamlessly with vim (Linux / Mac / Win), sublime (Linux / Mac / Win), gedit (Linux / Win), & less (Linux / Mac). After installing bioSyntax files will automatically detected by file-extension.
For very large data sets, it’s often slow to open them in a text editor. It’s best to use the command-line program less which will read your file from a data-stream.
Read your large-data set with less directly
# If your file is uncompressed, it can be read directly. # less will recognize the file extension (.XYZ) cd ~/myData/ less dbSNP107_common.vcf less hg19.fa
Streaming your data directly into less with pipes
# If your file is compressed, you can 'pipe' the data # using the "|" operator from decompression, directly into # less. You must prefix the file extension you want # as file formats are not recognized within streams. cd ~/myCompressedData/ samtools view -h NA12878_hg38.bam | sam-less gzip -dc dbSNP107_rare.vcf.gz | vcf-less gzip -dc hg38.fa.gz | fa-less
Bypassing bioSyntax (data in plain-text)
:syntax off in vim
# You may want to view your data without syntax highlighting # such as where a file is improperly formatted or very large # files where syntax highlighting may be slow (i.e. VCF files # with hundreds of columns). # 1. Pipe your data through cat cat snp_1000genomes.vcf | less - # 2. Within less, switch to a visual editor less snp_1000genomes.vcf # press 'CTRL-C' to stop process # press 'v' to switch to visual editor
bioSyntax implements a novel, full IUPAC Nucleotide Code coloring. Ambiguous bases are represented by an ~additive color-mixing of the parent bases. For example, Thymine (blue) + Cytosine (red) are both pYrimidines (magenta).
An intuitive feature of the bioSyntax color scheme is that the ‘GC-content’ of a sequence can be quickly approximated by how warm (high GC, red-orange) or cool (low GC, blue-green) a sequence looks.
When available, bioSyntax will highlight PHRED quality scores in a step-gradient of blacks (PHRED = 0-10) to whites (PHRED = 40+).
.sam files the Query:Reference alignment is summarized efficiently but illegibly as a CIGAR String. With a little bit of highlighting these become much easier to read.
Amino Acid Color Schemes
You can choose from several color-schemes for amino-acid fasta files. The
Fasta Clustal (Default) syntax colors amino acids based on their physiochemical properties, so does
Fasta Hydrophobicity, or you may prefer better discrimination of each amino acids with
Fasta Zappo or

Report a bug / Ask a question
The fastest way to get an answer is to:
1) Search / Open an issue on the bioSyntax Repo.
- A detailed and descriptive title.
- Enough information about what did for someone else to replicate the problem.
- Information about the operating system / software you’re using (
- If it’s a syntax highlighting issue: a screenshot of the error and a small bit of the input file you used.
2) If you really don’t want to make a (fake) github account. Email [email protected]ntax.org and we’ll open the issue, but it will be slower.
Collaborating on bioSyntax
bioSyntax is a community-oriented project for scientific syntax highlighting. We encourage you to change and customize it to suit your needs.
Check out the Development page to create syntax-highlighting for custom file-formats and for other ways to help out.
