XL-Plot 2.99
Create your publication-ready graphs rapidly with XL-Plot. more>> The primary purpose of XL-Plot is to create a figure rapidly. It is ideal for for use at high school, as the path from data in one or more spreadsheet columns to the final figure is short (just a few mouse clicks) and easy to grasp.
It contains basic statistical functions, such as Students t-test and linear correlation of two sets of data (two columns in a spreadsheet). XL-Plot has a number of build-in functions that can be fitted to the data in columns on a spreadsheet or to a curve in a graph. The user can easily add fitting functions of his own design.
Additional options are Fourier transformation, (de-)convolution, eigen decomposition and matrix inversion.
Features.
Simple, intuitive "visual" program layout.
Fast: No useless options, few dialogue windows, lots of short-cuts and hence a minimum of mouseclicking to do, resulting in a gain of time.
The program is build around two types of window each having its own menu:
1) Windows showing vector drawings (drawing sheets).
2) Windows showing columns of numerical data (spreadsheets).
Items in the last two types of window may communicate such that a modification in a column in a spreadsheet results in a change in the associated vector graph, allowing easy editing.
By using copy and paste functions from the menu, data from either window may be copied to a spreadsheet or to a drawing sheet resulting in a column of numbers or a graph respectively.
The math library contains many useful functions such as convolution and deconvolution, Fourier transform, matrix inversion and eigen decomposition of a matrix.
Statistical tests for data in spreadsheet columns: linear correlation, chi-2 test, Students t-test, Fishers F-test, Tukeys q-test (one-way anova).
Bitmaps may be imported and manipulated on the drawing sheet.
Graphics may be exported to other vector drawing programs.<<less

Analysis of electrophysiological data for MS-Windows. more>>
Serf 3.03 is created as an excellent tool which is like an analysis of electric-physiological data for MS-Windows 95, 98, 2000 and XP. It accepts ASCII data, ISO-2 data and files in AxonInstruments formats for the PC (PClamp, Fetch etc) and the acIntosh (Axograph type 1 and 2). It has an interface for use with Media Cybernetics IP+ scripts. It outputs a vector drawing ready for publication.
Major Features:
- Simple, intuitive "visual" program layout.
- Fast: No need to switch between multiple programs to obtain your figure at last, no useless options, few dialogue windows, lots of short-cuts and hence a minimum of mouse-clicking to do, resulting in a gain of time.
- The program is build around four types of window each having its own menu:
- Windows showing the raw input records (input windows).
- Windows showing wav records (sound windows).
- Windows showing vector drawings (drawing sheets).
- Windows showing columns of numerical data (spreadsheets).
- Items in the last two types of window may communicate such that a modification in a column in a spreadsheet results in a change in the associated vector graph, allowing easy editing.
- The concatenated mode of plotting of input data allows a quick overview of an experiment.
- The path from input to graph may involve a single step or multiple steps using a spreadsheet to hold and manipulate temporary data.
- Curve fitting using either build-in or user-defined functions can be carried out in each of the three types of window.
- The math library contains many useful functions such as convolution and deconvolution, Fourier transform, matrix inversion and eigen decomposition of a matrix.

ImageSurfer 1.2
ImageSurfer is developed as a free 3D imaging program for microcopy, which lends investigators ability to visualize and analyze multi-channel 3D and 4D (time-lapse) volumes. more>>
ImageSurfer 1.2 is developed as a free 3D imaging program for microcopy, which lends investigators ability to visualize and analyze multi-channel 3D and 4D (time-lapse) volumes.
ImageSurfer provides several image restoration tools including deconvolution algorithms (Wiener filter, constrained iterative and maximum likelihood) to remove blurring introduced by the imaging system.
For visualization, ImageSurfer provides several volume and surface rendering techniques. The software also has an innovative colored isosurface mode that provides a qualitative display of the correspondence between two channels.
A "slice extractor" enables the user to examine a cross section of the volume taken at any orientation. The captured slice can be visualized as a traditional 2D image or as a 3D-relief representation in which the image intensity is coded as height. To further probe spatial overlap between structures, the investigator can use data from another channel to colorize the 3D relief representation.
For quantification, signal intensity values can then be sampled within captured slices along a user-defined spline. In addition to taking snapshots of 3D representations and generating movies, 3D models can also be exported as OBJ or VRML (virtual reality modeling language) files; VRML files can be viewed within Web browsers using a free plug-in.
Both file types can be imported into popular 3D rendering programs for further processing, and into Acrobat 3D to produce documents that can be viewed interactively with Adobe Reader 8.
