[Aqualist] new palaeoecological software

[Simon Haberle]

Dear Listers

Apologies for cross-posting...

Those of you interested in software for developing palaeoecological
transfer functions or plotting stratigraphic diagrams may like to take a
look at my new program C2, which is now available for download at:
http://www.campus.ncl.ac.uk/staff/Stephen.Juggins/software/c2home.htm

C2 Version 1.3 is a Windows 95/98/NT/2000/XP program for analysing and
visualising palaeoenvironmental data. The main features are: (1)
develop, diagnose and apply transfer functions using weighted averaging
(WA), partial least squares (PLS), weighted averaging partial least
squares (WAPLS), Imbrie & Kipp factor analysis, correspondence analysis
regression (CAR), principal component analysis regression (PCAR), modern
analogue teachnique (MAT), and maximum likelihood regression and
calibration (ML), all with leave-one-out, bootstrap or n-fold leave-out
cross-validation and sample-specific reconstructions errors, (2) create
x-y scatter, line and bubble plots to visualise species environment
relationships and to diagnose fitted models, (3) plot stratigraphic
diagrams with bar, line, silhouette and symbol graphs, overlay multiple
series on the same axes, each with optional error bars, and the ability
to combine multi-proxy data from different datasets measured at
different time or depth intervals in the same diagram, (4) scale
graphics in absolute units (mm) or fit to page, and cut & paste diagrams
to a favourite drawing package, and (5) import / export data to / from a
range of common formats including Excel, Access, Tilia and Cornell, and
ability to edit, sort, transform and merge datasets. A more detailed
description of the program and a user guide can also be found on my web
pages. The program download consists of a single executable that will
install the program, help files, user guide, tutorial, and example
datasets. C2 replaces my previous programs CALIBRATE, WAPLS, MAT and
PDP.

C2 is free to download and use but the data analysis and graphics
functions are restricted to a maximum number of 75 samples. A license
file that removes this restriction must be purchased to use C2 with
larger datasets. The data editing functions in C2 are not
size-restricted.

Thanks, Steve
