Convert BB to another file type
To convert BB Data files to another format, you need UCSC Genome Browser or other Data software.
Convert a file to BB
To convert other file formats to the "Genomic Data File" file type, you need software like UCSC Genome Browser or a similar tool.
About BB files
The .BB file extension primarily represents a bigBed genomic data file. These files are used by the UCSC Genome Browser to store large amounts of continuous genome sequence annotations. By storing data in a binary, indexed format rather than a standard text file, the browser only loads the required data chunks, saving memory and bandwidth. Secondary uses for the .BB extension include game data and scripts for MDickie video games, baseband radio signal recordings used by the MATLAB Communications Toolbox, vulnerability scan profiles for the Burp Suite Pro Burp Bounty extension, and source code for Blitz BASIC.
The primary disadvantage of a .BB file is its heavily specialized and often proprietary nature. A bigBed file is unreadable in standard text editors. It requires specific bioinformatics command-line tools, like bigBedToBed, to extract the data. MDickie game scripts and MATLAB baseband signals are closed binary formats, meaning you need the exact original software to parse them properly. Burp Bounty files use standard JSON formatting under the hood, but the obscure extension confuses standard desktop applications.
Users often need to convert .BB files to standard formats for analysis. Genomic bigBed files convert to text-based BED files. Blitz BASIC files and Burp Bounty profiles convert seamlessly to TXT or JSON. For baseband signals and game scripts, conversion targets vary and often risk losing embedded metadata.
This file format is notoriously difficult to open or convert because multiple completely unrelated software programs share the same extension. A general online converter fails because it cannot guess if the file contains DNA sequences, radio frequencies, or video game variables.
Convert.Guru analyzes your BB file, detects the exact format, and lets you read the text inside.
Users also converted BIN, JPG, WIG, BEDGRAPH, BIGBED, BED and FB files.
FAQ
If you want to convert BB file to BED, FB, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB or GO, you can use UCSC Genome Browser or similar software from the "Genomic Data Storage" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to BB, try UCSC Genome Browser or another comparable tool in the "Genomic Data Storage" category.
The BB Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BB converter.
