XPST is a program package for the analysis of X-ray Photoelectron Spectroscopy (XPS) data. It includes various graphical interfaces as well as commandline functions to facilitate the workup of XPS data.
A simple procedure file that creates a panel with calculators for determining the molarity of a stock solution. Also includes a calculator for solving for a dilution when making a working solution from a stock solution. Each calculators include dropdown menus for changing the units of the measured volume and weight. Compiling the procedure places a link in the Macros menu.
This program predicts the electrostatic force between two identically charged solids in solution, by numerical solution (Runge-Kutta) of the Poisson Boltzman equation (It provides solutions for both constant charge and constant potential assumptions). The electrostatic + van der Waals force (DLVO force) between the solids is also available by addition of a van der Waals Force (which accounts for a retardation of the Hamaker constant as function of distance).
The ‘Graph Control’ package is a visualization utility to show the main attributes of Igor graphs and traces.
It allows quick manipulation of trace style, replacement, reordering and editing of selected traces, error bars parameters and easy work with data folders and multiple axes.
Plot attributes, as well individual and multiple traces can be copied and shared between graphs.
Additionally, the package allows for trace transparency and opaque overlay of multiple traces.
Code to downsample neuronal morphologies generated in SWC format, for example by the simple neurite tracer in FIJI.
Load your SWC file as a 7 column wave
Call "Prune(SWC, spacing)"
where SWC is your neurone and spacing is your desired 3D distance between points.
Will generate a new wave called pruned and show you a projection of the two waves.
iPhys is a dual image analysis / electrophysiology acquisition and analysis suite. Readable formats include TIFF image files, text data files and iPhys generated data files. The software was developed with increased automation of basic procedures in mind. For example, the user doesn't need to specify a file name for saving acquisition files, as they are automatically saved into the working directory. The user enjoys an extensive graphical interface with sticky windows (making dragging multiple windows easy), easy to activate and close plots and one click generated complex analysis modules.
Adds the ability to generate fuzzy (blurred) lines to graphs. Parameters (width, color, line style) are controlled by Fuzzy Line panel from the Graph menu. Individual traces can be selected by right clicking the trace and selecting Fuzzy line. Currently only similar parameters for all traces on a plot is supported. Fuzzy lines are updated when traces change, but only when Fuzzy Line panel is visible.
This project serves to measure the dynamics of actin fibers using a bleach zone and/or bright fiducial point as points of reference. Actin fiber can be photo-marked using localized photo-bleaching. A region of interest along the actin fiber is to be used for the generation of a kymograph. The bleach zone is seen as a dark band in the kymograph, while bright fiducial point on the actin fiber is seen as a bright band. This script generates a kymograph based on Tif movie. It divides the kymograph into upper and lower part.
FitXPS is a procedure to fit a core-level X-ray photoemission spectrum (XPS) to a Voight profile with Shirley or Tougaard type background.
This package provides a way to show the pressure - molar volume isotherms for a range of gases that follow the van der Waals gas law. It was created as part of assignment for a course on thermodynamics, specifically dealing with mechanical equations of state for real gases.
iSpectra is an open toolbox for the analysis of spectral images (SI's) recorded on scanning electron microscopes (SEM's), equipped with energy dispersive spectroscopy (EDS) systems for chemical analysis. iSpectra provides various tools for visualising chemical variability within a SI but is primarily written to create true phase maps, rather than more commonly used elemental x-ray distribution maps. iSpectra imports SI's in Lispix format and exports cumulative phase spectra in industry standard EMSA format along with graphical output.
Chebyshev performs interpolation and fitting using Chebyshev polynomials
This package allows the user to easily create their own custom colour tables for use in other Igor plots (either to define colours in image plots, or for colouring traces/data-points).
The interface allows the user to create four distinct types of colour table:
- Single Hue table
- Bi-polar (Double Hue) table
- Multi Hue Category table
- Hue Blend table
This routine calculates the number of bytes in a selected data folder, including any subfolders. It builds on the recursive listing functions written by Jamie Boyd. The output is printed to the history window in a human-readable format. The calculation considers only numeric waves, not text waves and not strings or variables.
Zoom in/out of graph with scroll wheel (both x and y simultaneously), centered around mouse cursor.
Tries to zoom only relevant axes; should do ok with single plot graphs or graphs with plots in single row or column. Might not do so well if there are multiple columns and rows (a matrix of plots).
- Activate on each graph or automatically enable on all _new_ graphs.
- Activate/automatically-enable in Graph:Packages:Scroll Zoom menu or in Graph Marquee popup menu (is there a way to append to the Graph popup menu?).
Reconstruction of the spatio-temporal receptive fields of visual neurons with filtered back projectionPosted August 6th, 2014 by inchinn
This project provides procedures to reconstruct both the spatio and temporal receptive fields of visual neurons that have been stimulated with a series of flashed bars.
A complete description of this method along with examples of its implementation has been published in a scientific paper in J Physiol (2014) doi:10.1113/jphysiol.2014.276642 (http://www.ncbi.nlm.nih.gov/pubmed/25172952).
Please cite this paper when publishing data using this method.
Igor implementation of "Dave Green's `cubehelix' colour scheme" described here:
This colour scheme is described in more detail in:
Green, D. A., 2011, `A colour scheme for the display of astronomical intensity images', Bulletin of the Astronomical Society of India, 39, 289.
(http://adsabs.harvard.edu/abs/2011BASI...39..289G at ADS/)
This implementation has a panel where you can design a "cube helix" color index wave and apply it to any open image plot.
bpc_ReadAbf is an Igor Pro extension (XOP) that allows one to import pClamp ABF 1.x and 2.x binary files into Igor Pro.
bpc_ReadAbf is compatible with Igor Pro 32bit running on Windows 32bit or 64bit, it requires Igor Pro 5 or later.
Molecular Devices Corp, the company selling pClamp, provides a file support package (FSP) to aid software development. This FSP
is available for 32bit Windows only. I created a very simple XOP that basically wraps some of the functions provided by the FSP.
This is a general project for importing data files from various instruments/software.
