PAZ Software develops specialty scientific software solutions for Mac OS
Although the software is specifically for MacOS, all input and output (data and graphics files) are cross-platform (i.e. compatible with Mac, Windows, Unix, etc.). PAZ software applications were developed for geological, biostratigraphic and earth science needs, however, they are often purchased and used for a broad range of applications in other disciplines.

WellPlot 3.5 is a stratigraphic data analysis and charting application that plots multiple categories (up to 600 columns) against depth or sequence of samples. Data is read directly from spreadsheets. Sums, percentage and concentration data may be calculated and saved. Plot types include: multi-track x-y line plots (log style), butterfly diagrams, bar charts (log style), interval histogram range charts, range-through charts, percent events plots and cumulative data plots. The Y-axis (depth) can be scaled to depth or sequential samples. The X-axis can be normal (arithmetic) or LOG scale, and absolute or normalized. Exaggeration may be applied to low abundance groups. The charts can be scaled to any horizontal and vertical dimensions. Wall-size charts to page-size charts. Sort categories by first occurrence, last occurrence, alphabetically, by maxima, by species codes or as originally entered. Use WellPlot to plot all types of well data e.g. geochemical or petrological. WellPlot is updated often. Current owners should contact about eligibility for a free update. See detailed description for many new features. New lightning fast data loading! 

Counter 3.5 is data acquisition and quality control software that emulates a manual counter. Users report that the speech feedback and other features allow a 4X increase in the number of samples counted. The built in quality control ensures the best balance between statistical validity and the time taken to collect the data. Spreadsheet-like functions include: Add, insert, and delete both samples and categories; Edit counts for any category in any sample at any time; Edit any category or sample name at any time. Other functions: Add or subtract counts by 1 or 10 counts per click; Distinct audible sounds for add and subtract; user defined Interval alert (audible tone); A histogram of any sample may be viewed and printed and a growth chart is drawn for the active sample. Multiply counts above a cut-off; With speech installed, Counter will speak the category name as it is tallied. See detailed description.

Counter 3.5: MacOS Data acquisition (and quality control) software that emulates a manual counter. Count up to 250 categories per file. Many spreadsheet-like functions. Histograms, data growth charts, etc. Speaks category names for audio feedback of counts. Improves data quality and speeds acquisition.
MiniCounter 1.0: MacOS Data acquisition software. MiniCounter is a limited version of Counter 3.0 that tracks only 10 categories in one sample.
ShawPlot 1.05: MacOS Graphic correlation: Cross plot common events between 2 wells and plot graphic correlation diagrams. Use optimum scaled sequence (from RC-RASC) as standard section.
RC-RASC 1.02: MacOS Finds the optimum sequence of ranked and scaled events from multiple files of taxa events. Use ShawPlot to cross plot events against optimum scaled sequence. 
LookUp 1.05: MacOS Provides for interaction between WellPlot and stratigraphic databases via look-up tables. Multiple species copied from a range chart may be looked up allowing for interactive analysis of species distributions. Built-in geologic time scale (SEPM, 1995, Gradstein and Ogg, 1996).
Age/Depth 1.07:MacOS Plot event depth against geologic age of event. Built-in geologic time scales (SEPM, 1995, Gradstein and Ogg, 1996). Graphic correlation-like. Interactive "lines of correlation". Edit data: depth, FAD, LAD, etc.
This product is no longer for sale. Age-depth analysis service is available from
Diversity Calculator 4.0: MacOS
New version!
Calculate ten common diversity indices and total abundance from spreadsheet data.
