Free mass spectrum software for linux

MassSpec::ViewSpectrum is a Perl extension for viewing a mass spectrum.

SYNOPSIS

use MassSpec::ViewSpectrum;

open PNG, ">mygraphic.png" or die "Unable to open output filen";
binmode PNG;

my @masses = (1036.4,1133,1437,1480,1502);
my @intensities = (0.1,0.15,0.05,0.10,0.2);
my @annotations = (b,w,internal w, ,internal y);

my $vs = MassSpec::ViewSpectrum->new(@masses,@intensities, @annotations);
$vs->set(yaxismultiplier => 1.8); # a sample tweak to adjust the output
my $output = $vs->plot();

print PNG $output;
close PNG;

MassSpec::ViewSpectrum - Perl extension for viewing a mass spectrum, e.g. typically obtained from the fragmentation of proteins or peptides.

At present this is only implemented using GD graphics, but in principle this could be subclassed in the future to include alternative graphic paradigms such as SVG and Tk.
The current implementation uses a mixture of GD::Graph and native GD, since GD::Graph 1.43 fails to draw the required vertical lines correctly.

Negative peak intensity values are permitted; this permits the drawing of "pseudospectra" which, for example, illustrate peaks present in one spectrum but missing in another.

FFT Spectra is a tool for the visualization of frequency spectra of an audio signal.

Among other things, it can be used to verify whether you are able to sing and whistle in tune or to tune your guitar.

Examples:

Didgeridoo

Didgeridoo is actually the reason, why i started writing this software. The theory of physics explains that when you blow into a cylindrical tube (such as didgeridoo, but PVC pipe works as well) and vibrate your lips, standing waves develop inside the tube.

At that end of the tube, where the air leaves, there is nearly atmospheric pressure and the standing wave has a node there. At the other end, where one blows the air in, the changes in pressure are maximal and the standing wave must have an antinode here.

The situation is depicted on the picture on the right: The horizontal axis represents a position along the tube and the vertical axis represents a maximal pressure variation from the constant atmospheric pressure. The black vertical line represents a zero variation. The left black point is the mouth-side enpoint of the tube. The pressure variation are maximal here. The black point on the right is the open side od the tube - the pressure is constant here.

This node/antinode restriction permits only standing waves with appropriate wavelength (e.g. frequency) to be developed. Other frequencies are forbidden. So, the red curve is a minimal (fundamental) frequency, which is present in the didgeridoo sound. (Corresponds to 70Hz on the picture bellow).

If we squeezed the red curve twice, i.e. made the frequency twice as high, on both end-points there would be an antinode and the node/antinode constrain would not be fulfilled. Really, we see that the peak at 140Hz bellow almost disappears. If we squeeze the curve a little bit more to obtain the green curve, the boundary condition is again met and the peak at 210Hz is clearly visible bellow. And so on.

mass.pl is the implementation of a relatively simple idea. Instead of interactively doing some task on one machine, then duplicating the effort on N other machines, write a shell script, then scp it to N machines and execute it as root.

Example

(sic@foo)($:~/mass)- ./mass.pl --name solaris --script pushsomething --su --sshpass

Mass Rotate is a program that quickly and losslessly rotates JPEGs.

Its useful for rotating images from digital cameras. Uses jpegtran from from the Independent JPEG Group. Written in gtk2-perl.

Usage:

mass_rotate.pl dir_with_images/

or:

mass_rotate.pl image1.jpg image2.jpg image3.jpg ...

or:

mass_rotate.pl dir/ img.jpg other_dir/ whatever.jpg you_get_the_idea/

ID3 mass tagger is a portable command-line mass tagger for audio files.
ID3 mass tagger is designed for non-interactively adding, updating or removing meta-information in a number of files with a single command.
It can generate tag fields from the filename and rename files using an intuitive syntax. It currently supports ID3 (1.1) and ID3v2 (2.0, 3.0) tags.
Exemple:
Here are some examples of using id3:
id3 -a "Stallman" -t "Free Software Song" fs_song.mp3"
Add a simple tag to a file.
id3 -d *.mp3
Removes all ID3v1 tags from all mp3s
id3 -g "psych rock" *.mp3
Sets genre to "Psychedelic Rock" all mp3s
id3 -2 -1 -u "*.mp3"
Copy ID3v2 tag to ID3v1 tag in all files.
id3 -a "TAFKAT" -n "%1" -t "%+2" "*. *.mp3"
Update tag fields similar to this;
id3 -a "TAFKAT" -n "01" -t "My Song" "01. my_song.mp3"
id3 -a "TAFKAT" -n "02" -t "Untitled" "02. untitled.mp3"
id3 -2 -f "%a - %t.mp3" blaet.mp3
Rename file to a standard "Artist - Title" format, using ID3v2 values.
id3 -g "alt rock" -a "The Author" -l %1 -n %2 -t %3 "Author - */(*) *.mp3"
Process multiple directories at once.
id3 -g "alt rock" -a "The Author" -m "Author - %l/(%n) %t.mp3"
Shorthand for the previous example.
id3 -a %t -t %a "*.mp3"
Swap artist and title fields in all mp3s.
id3 -D source.mp3 -1 -2 dest.mp3
Copy ID3v1 and ID3v2 tags of source.mp3 to dest.mp3
id3 -D source.mp3 -1u -2u dest.mp3
As above, but only replaces the non-standard or blank fields in dest.mp3 by data from source.mp3.
id3 -2 -rAPIC -s 0 *.mp3
Removes embedded images and padding from all mp3s.
id3 -2 -rAPIC -s 0 -R "*.mp3" "/my documents"
As above, but works recursively on all mp3s in the directory tree starting at /my documents
id3 -2 -q "%| %a - %|Untitled|t || %t || %1 |?" "*.mp3"
Generate a playlist, using the best possible text
id3 -2 -c "Was: %_f" -f "%a - %|Untitled (%#x)|t.mp3" "*.mp3"
Advanced rename. Saves previous filename in the comment field, and renames files without proper tags to;
Unknown - Untitled (01).mp3
Unknown - Untitled (02).mp3
... etc
Enhancements:
- This release adds support for Lyrics3 tags.

SpectraScan is a little helper program for those unlucky persons, who dont get their spectrums in an appropriate computer readable format, but on dead tree.

This project allows to convert a variety of spectrum types into a comma separated value format, which is suitable to be loaded into Excel or a statistic program.

Another feature is the ability to scan the axes of a spectrum.

Metal Mech is a fully web-based mass multiplayer game of battle between robots and space exploration. Metal Mech is a game of strategy, economic, role-playing and combat.

Each player can handle own war robot and battle against other players to be the Emperor of the Universe. Players war against each other for resources, energy, money, buildings and other.

In the game players can build fabrics, mines, buildings and product robots, weapons, devices & etc. Also players can trade with each other.

Project will be fully written in PHP and XML(XSLT).

Critical Mass (aka Critter) is an SDL/OpenGL space shootem up game. Critical Mass project currently runs on Mac OS X, Windows, and Linux.

The latter is my main development platform. Other platforms supported by SDL/OpenGL may also work with a bit of work.
