DELIMINATE Test

Today I saw the abstract for a new compression algorithm in my RSS feed. I thought I would give it a try and compare it to other compression programs: gzip, bzip2, and zip.

While this new algorithm, DELIMINATE, is much slower at decompression than the others, it is much quicker at compression and achieves the best compression ratio. Note: this video limits the idle time for each command to 5 seconds, so just refer to the runtimes on the command line for comparison.

The paper is available at http://bioinformatics.oxfordjournals.org/content/28/19/2527.short. The program was easy enough to obtain and use and worth consideration for managing NGS data. There is still the practical question though of whether the improved compression speed and compression ratio warrants having yet another compression program accessible on every system you frequently use, especially given the slower decompression speed.

</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/1331.cast',
      document.getElementById('player'),
      { cols: 110, rows: 30 }
    );

See asciinema player quick-start guide for full usage instructions.

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/1331 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
