Dear all,

I am pleased to announce the 10th release of GNU Astronomy Utilities
(Gnuastro 0.10).

Gnuastro is an official GNU package of various command-line programs
and library functions for the manipulation and analysis of
(astronomical) data. All the programs share the same basic
command-line user interface (modeled on GNU Coreutils). For the full
list of Gnuastro's library, programs, and a comprehensive general
tutorial (recommended place to start using Gnuastro), please see the
links below respectively:

https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html
https://www.gnu.org/s/gnuastro/manual/html_node/General-program-usage-tutorial.html

Many new features have been added, and many bugs have been fixed in
this release. For the full list, please see [1] below (part of the
NEWS file within the tarball). Some of the highlights are: 1) You can
now do column arithmetic (on FITS and plain text tables) directly
within the Table program, it also has some operators unique to table
columns for example conversion of pixel to world coordinate system
(WCS) coordinates and vice-versa. 2) Crop can now be used to pull out
sections of 3D data cubes also. 3) You can let CosmicCalculator find
the red-shift by identifying an emission line's wavelength or name,
and its observed wavelength.

Here is the compressed source and the GPG detached signature for this
release. To uncompress Lzip tarballs, see [2]. To check the validity
of the tarballs using the GPG detached signature see [3]:

For this release, I am very grateful to Alexey Dokuchaev, Joseph Putko
and Raul Infante-Sainz for direct contributions to Gnuastro's
source. Hamed Altafi, Roberto Baena Gallé, Zahra Bagheri, Leindert
Boogaard, Bruno Haible, Raul Infante-Sainz, Lee Kelvin, Elham Saremi,
Zahra Sharbaf, David Valls-Gabaud and Michael Wilkinson (in
alphabetical order) also provided very good suggestions and bug
reports, I am very grateful to them.

If any of Gnuastro's programs or libraries are useful in your work,
please cite _and_ acknowledge them. For citation and acknowledgment
guidelines, run the relevant programs with a `--cite' option (it can
be different for different programs). Citations _and_ acknowledgments
are vital for the continued work on Gnuastro, so please don't forget
to support us by doing so.

This tarball was bootstrapped (created) with the tools below. Note
that you don't need these to build Gnuastro from the tarball, these
are the tools that were used to make the tarball itself. They are only
mentioned here to be able to reproduce/recreate this tarball later.
  Texinfo 6.6
  Autoconf 2.69
  Automake 1.16.1
  Help2man 1.47.10
  ImageMagick 7.0.8-58
  Gnulib v0.1-2794-gc8e2eee54
  Autoconf archives v2019.01.06-55-gc5711b3

In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus.

In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types.

Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence.

Solving computational problems was the first inspiration behind the invention of computers. Although modern computers have come a long way since its inception, it continues to play the de-facto role in solving complex computations. A Computer Algebra System (CAS) is a software environment that allows tackling modern-day, complex computational problems without having to manipulate complicated equations or computational systems manually. These computer algebra systems can manipulate mathematical formulae in a manner similar to traditional mathematicians and thwarts away potential errors effectively. There are a wide variety of computer algebra systems for Linux, both general-purpose and specialized.
