6. Changes in Fedora for Specific Audiences

6.1. Scientific and Technical

6.1.1. ATpy

ATpy is a Python library for manipulating astronomical tables. Details are available at

6.1.2. bowtie

bowtie is an ultrafast, memory-efficient short read aligner. It aligns short DNA sequences (reads) to the human genome at a rate of over 25 million 35-bp reads per hour. Bowtie indexes the genome with a Burrows-Wheeler index to keep its memory footprint small: typically about 2.2 GB for the human genome (2.9 GB for paired-end).

6.1.3. DSDP

The DSDP software is a free open source implementation of an interior-point method for semidefinite programming. It provides primal and dual solutions, exploits low-rank structure and sparsity in the data, and has relatively low memory requirements for an interior-point method. It allows feasible and infeasible starting points and provides approximate certificates of infeasibility when no feasible solution exists. The dual-scaling algorithm implemented in this package has a convergence proof and worst-case polynomial complexity under mild assumptions on the data. For full documentation refer to

6.1.4. fastx_toolkit

fastx_toolkit is a collection of command line tools for Short-Reads FASTA/FASTQ files preprocessing.

6.1.5. IBSimu

Ion Beam Simulator or IBSimu is an ion optical computer simulation package for ion optics, plasma extraction and space charge dominated ion beam transport using Vlasov iteration. More information at

6.1.6. gappa

gappa is a tool intended to help verifying and formally proving properties on numerical programs dealing with floating-point or fixed-point arithmetic. Fedora 16 upgrades to version 0.15.0. The project's web site may be found at

6.2. Amateur Radio

6.2.1. ax25-tools-x

ax25-tools-x provides a GUI interface to various soundmodem configuration and diagnostics applications.

6.2.2. cutecw

cutecw has been updated to 1.0. Improvements include better training sequences, a greatly improved "read-to-me" mode, and a number of cosmetic enhancements. For more information refer to

6.2.3. hamlib

hamlib has been updated to version Some of the significant features are:
  • support for VX-1700, FUNcube, FiFi-SDR, KTH-SDR Si570, FT-5000, TS-590S
  • A new rotor backend with new features
  • Fixes and new features for TS-440S, K2, K3, SR-2200, THF6A, THF7E, NewCAT rigs serial port defaults, TM-D700
  • Allow USB device's VID/PID/Vendor/Product to be explicitly specified
The complete upstream changelog is available at and there is more general information on the project's wiki at

6.2.4. xnec2c

xnec2c version 1.5 incorporates a number of improvements over 1.2:
  • removed the restrictions in excitation to allow plotting the re-radiated pattern from a structure excited by incident field or elementary current source
  • fix crashing of xnec2c 1.3 on long input file names (greater than 80 characters).
  • Changed the handling of command line arguments so that the input file name may be specified without the use of the -i option.
  • allow the calculation of front to back ratios when the antenna is modelled over ground.
