ALP Alternate Line Profile

Last changed: 17 weeks 1 day ago

Why ALP?
The Igor 7 image line profile has fewer features than in Igor 6. Wavemetrics is not currently planning to make significant changes, the
workaround suggested is to use IP6 procedures. Some issues are:
- The profile graph cannnot be modified, or the data explored, for example with a cursor.
- Does not take wave scaling into account.
- No longer possible to graph a profile, it can only be saved. (Has been changed in Igor 7.02)
- The saved wave is now a triplet. This is not visible in the default New Graph menu, inexperienced users can not easily graph it themselves.

Clementine, package for modeling decay kinetics using MEM and Least square fitting

Last changed: 5 years 46 weeks ago

Clementine was developed to model decay kinetics processes using either maximum entropy (MEM, included) or least square fitting. The math of analysis (decay times are "tau") is :
MEM: signal(time) = FlatOffset + sum (P(Tau) * exp(- time/tau))
LSQF: signal(time) = FlatOffset + sum (P(Tau) * exp(- (time+TimeShift)/tau))
The package will :
MEM : Generate the distribution of P(Tau) values using Maximum Entropy method over user defined number of bins in tau (log-spaced)
LSQF : Model (and least square fit) sum of for up to 5 different P(tau), TimeShift, and tau combinations. Both P(tau) and tau can be fitted.

DLVO Fitting Program

Last changed: 2 years 7 weeks ago

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).

EccentricXPS - Analysis and Organisation of XPS Spectra

Last changed: 11 weeks 5 days ago

EccentricXPS is an Igor Pro procedure initially written to load, display and analyze the two-dimensional x-ray photoelectron spectroscopy (XPS) images produced by our VG Scienta SES 200 hemispherical analyzer at the University of Erlangen-Nuremberg. EccentricXPS can load and display the images from the raw .txt files produced by the SES software (version 1.2.2, build 37) and then convert the images to normal one-dimensional spectra, which can be easily displayed, compared and fitted, either as single spectra or in bulk.


Generalized Linear Model Fitting

Last changed: 4 years 29 weeks ago

This implements generalized linear models in a function glmfit. Support for unity-link (gaussian distribution), log-link (poisson distribution), and logit-link (binomial distribution), and tan-link (von mises distribution). General usage given in function TestGLMFit, with a log-link (poisson) example. It is best to just contact me directly for support.


Generalized Spike Sorting Explorations

Last changed: 7 years 43 weeks ago

This is a set of two procedures that extract spike waveforms from raw electrode traces and then perform principal component analysis and clustering on the extracted waveforms. The resulting classified spike times and spike shapes are displayed along with a rotatble Gizmo scatter plot of the first 3 principal components. This is a very early version and is likely full of bugs and inefficiencies.


HITRAN procedures for Igor

Last changed: 3 years 40 weeks ago

Last changed: 2 years 7 weeks ago

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.


IR Shifted-peak fitting

Last changed: 22 weeks 4 days ago

This is a set of routines designed to fit temperature-dependent amide I infrared spectra of proteins and peptides. It has been shown that these peaks are temperature-dependent. The data is fit to a sum of Gaussian peaks, with center position and width of each peak assumed to shift linearly with temperature. In addition, the model allows an equilibrium between peaks, so that each peak may (optionally) increase or decrease in amplitude with temperature. The change in amplitude with temperature is modeled as a two-state equilibrium.


iSpectra: A Toolbox for the Analysis of Spectral Images recorded on SEM-EDS systems

Last changed: 1 year 35 weeks ago

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.

The XOP includes operations for a full analysis, including:

MATLAB Functions

Last changed: 6 years 42 weeks ago

The biggest barrier to Igor adoption is usually knowledge of another environment's language. One of these is MATLAB. If a MATLAB users sits down to write Igor code, sometimes they have a hard time figuring out what the equivalent function in Igor is the function they know in MATLAB. And even if they find that function, if they haven't programmed in Igor, they might get stuck on the syntax.

    Periodic Table Selector

    Last changed: 16 weeks 4 days ago

    Periodic Table Selector (PTS)

    What and Why:
    J. J. Weimer has contributed the very nice Periodic Table Menu package. It shows data for one element at a time, but I needed a way to quickly select several elements. PTS is derived from Periodic Table Menu and has the following characteristics:

    - Graphically select any number of elements, the resulting list is processed separately.
    - Use mouse clicks or very fast mouseover to select or deselect elements.
    - Panel can be rescaled (as in Periodic Table Menu).
    - Panel can be closed, then later reopened, the selection is retained.


    pFLIM - an analysis program for time-domain fluorescence lifetime imaging microscopy (FLIM) data

    Last changed: 4 years 33 weeks ago

    We have developed a highly accurate and efficient code for the analysis of time-domain FLIM data (‘‘pFLIM’’ for precision FLIM). Our analysis code accounts for all significant instrumental artifacts (e.g., the instrument response function (IRF) and spatially inhomogeneous background events) and is rigorously based on both conventional and novel statistics. The code is described in detail in the manuscript:
