MySQL Local and/or Remote Backup
The name says it all.
...I made this because it was easier for me to create a whole new Perl script than to improve upon his bash goodness. Right now you can expect it to save databases (via mysqldump or mysql with a custom query) and upload them using FTP (via a Perl module). For compression management or auto-pruning of old backups you'll have to come back later. -

Hierachical_DNAcoder
An Hierachical Approach to Multi-Reference Genome compression
The storage and data transferring of large genome data are becoming important concerns for biomedical researchers. We present a novel multi-reference based genome compression method with a hierachical structure. Our approach works for the de facto standard alignment format (i.e., BAM) compression that is the pressing need at present. We align new sequences to a reference sequence using SOAP3, a GPU-based aligning software, and summarize mapping properties and information for exact mapped reads. To increase the exact aligning rate, we also realign the approximately mapped and unmapped reads by changing the reference sequence or shortening the read length. ... -

DNAcompact
Genome compression algorithm with/without reference (Linux/Windows)
As the technique of acquiring genome sequences advances, the storage and data transferring of large genome data are becoming important concerns for biomedical researchers. We propose a two pass genome compression algorithm, which highlights the synthesis of complementary contextual models and the introduction of logistic regression mixture method, to improve the compression performance. The proposed framework handles genome compression with and without reference seque- nces, and demonstrated performance advantage over the best existing algorithms. ... -

PyInstaller
Converts (packages) Python programs into stand-alone executables
PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. ... -

Arpeggio
Harmonic analysis of ChIP-seq experiments
Researchers generating new genome-wide data in an exploratory sequencing study can gain biological insights by comparing their data with well-annotated datasets possessing similar genomic patterns. Data compression techniques are needed for efficient comparisons of a new genomic experiment to large repositories of publicly available profiles. Arpeggio allows us to efficiently compare numerous ChIP-seq datasets consisting of many types of DNA-binding proteins collected from a variety of cells, conditions and organisms. Importantly, these interaction patterns broadly reflect the biological properties of the binding events. ... -

bmp2rle
Encode bitmap(bmp) file with run-length encoding
Encode bitmap(bmp) file with run-length encoding(RLE), just like RLE4 and RLE8, but extend to RLE16, RLE24 and RLE32. Usually, this project will be used in GUI of embedded system, to make the image files smaller, and save the IO bandwith. If the GUI support JPG or PNG, the compression ratio is much better than RLE, but how about the embedded system encounters both caculate limitation and IO bandwidth limitation? Try this project, I hope it can make a banlance between caculation and bandwidth. But first of all, you should know that the compression ratio of RLE is highly depend on the bitmap file data, the ratio can larger than 1, only when the same color continuously repeats in one line, it will gain a smaller compression ratio. -
