Mac ChiSquare Analysis calculates chi-square statistic as well as phi, contingency, and kappa coefficients from up to a 10 x 10 table.

The chi-square test is used to compare the distributions of two independent samples. It is used with data in the form of frequencies. It is a nonparametric procedure that makes no assumptions about distribution shapes, variances, or levels of measurement (Diekhoff, 1996).

The chi-square test evaluates the correspondence between the expected and the observed number of cases in each of the cells of the variable by variable contingency table (Thompson, 1988). It is a test of whether or not a null hypothesis of no association should be rejected between the two independent variables.

If the chi-square test shows that there is a relationship between the two variables, then the contingency coefficient gives an indication of the degree of the relationship. (Bruning & Kintz, 1997). The contingency coefficient is similar in meaning to the correlation coefficient.

Cramers phi coefficient is a measure of association that is also similar to a correlation coefficient. It can assume a value between 0 and +1. See Sheskin (2000) for further detail.

Kappa is calculated when the rows and columns are symmetrical. Kappa is often used to examine inter-observer agreement and reflects the amount of agreement beyond chance (Norman & Streiner, 2000).

Command line tool for comparing comma delimited data files using relative differences to determine the most similar conformations. Compsort compares the data files using relative difference, calculates a similarity score, sorts the scores in ascending order (lower values represent greater similarity), saves X number of low scores.
The data files produced by the user, must be comma delimited text files. Each file represents a unique molecule. Each row in a file represents a unique conformation of the molecule. The first column in the data file must be a label unique to the conformation represented by the row. The rest of the columns are numeric descriptors, such as distance space measurements.
The rows are compared combinatorially between files. The labels in comparison are concatenated and saved with the scores for the set of rows. This provides a way to identify the conformations which produced a given similarity score.
Enhancements:
- fixed a couple minor compiler warnings
- added reporting of calculation time for set of combinatorial calculations in addition to the previously reported sort time
- increased compiler optimization level of the binary.

ICC Examin is a colour management utility. Its unix name is iccexamin.
ICC Examin is configurable by Oyranos. Meaningful colours are drawn using the Oyranos monitor profile. Device dependent measurement data are visualized by requesting standard profiles from Oyranos and rendered to the monitor profile with littleCMS library.
ICC Examin may be called from CinePaint in order to examin embedded profiles or watch image colour samples in the images colour space gamut hull.
Main features:
- shows the internals of a ICC profile, like text, curves, 3D tables, colour coordinates...
- covers most of the ICC standard v2 tags plus some of version 4
- produces a profile quality report; as table or 3D view
- accepts measurement data (CGATS); visible as plain text or in 3D
- creates and accepts argylls gamut visualisations; vrml
- understands video card gamma tables (Xorg/XFree86/osX)
- accepts ICC named colour swatches (ncl2); shows as table or 3D

omnidea Rulers allows to create on whole screen area a set of rulers, like most common graphic editors allows on their working areas only.
Using the guide lines enables to measure and position objects with precision and its incredibly useful in many fields, such as computer graphics, desktop publishing and web design.
Rulers may also be used to select a screen area and take a screenshot that is automatically saved to desktop or copied to system clipboard.
Main features:
- Unlimited rulers creation
- Multiple units of measurement support
- Multi monitor support
- Take a screenshot of selected area or whole screen
- Magnifier
- Color picker
- Automatic internet update
- Available for Microsoft Windows and Mac OS X
- Available in English and Italian

Renal Growth - Designed to assist radiologists, renal physicians and paediatric urologists to plot renal length and volume measurements against nomograms for age and weight.
Calculate and monitor kidney growth
Store multiple observations from birth to 13 years. Length and volume charts can be exported as JPEG files, for importing into a PACS system or other clinical record.
Main features:
- Maintains database of individual patient files
- Export graphics as JPEG files or DICOM images to OsiriX
- Optional automatic update notification
- Optional script when launched

TurboMCS Controller is an application designed to interface with the EG&G Ortec TurboMCS (Multi-Channel Scaler) hardware via the serial port.
You have the possibility to view the data onscreen but also saved it in binary or text files. This type of hardware is used for fast timing measurements of pulsed count sources, mainly in LIDAR or other time-of-flight applications.

System requirements:
- Connected MCS.
