  Summary: Biospectrogam is an open-source software for the spectral analysis
of DNA and protein sequences. The software can fetch (from NCBI server), import
and manage biological data. One can analyze the data using Digital Signal
Processing (DSP) techniques since the software allows the user to convert the
symbolic data into numerical data using 23 popular encodings and then apply
popular transformations such as Fast Fourier Transform (FFT) etc. and export
it. The ability of exporting (both encoding files and transform files) as a
MATLAB .m file gives the user an option to apply variety of techniques of DSP.
User can also do window analysis (both sliding in forward and backward
directions and stagnant) with different size windows and search for meaningful
spectral pattern with the help of exported MATLAB file in a dynamic manner by
choosing time delay in the plot using Biospectrogram. Random encodings and user
choice encoding allows software to search for many possibilities in spectral
space.
  Availability: Biospectrogam is written in Java and is available to download
freely from http://www.guptalab.org/biospectrogram. Software has been optimized
to run on Windows, Mac OSX and Linux. User manual and you-tube (product demo)
tutorial is also available on the website. We are in the process of acquiring
open source license for it.
