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

Last changed: 31 weeks 1 day 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.

Generalized Spike Sorting Explorations

Last changed: 2 years 27 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.

Localizer - localization microscopy toolkit

Last changed: 42 weeks 2 days ago

Localizer provides a full package for performing localization analysis in superresolution fluorescence microscopy (PALM, STORM). The package comes in two parts, an XOP that is responsible for performing fast and efficient calculations, and an Igor procedure that provides a graphical front-end.

The XOP includes operations for a full analysis, including:
* Native loading of data from the manufacturer's file format for a range of scientific cameras (currently Photometrics, Andor, Hamamatsu, some Zeiss .lsm files, and grayscale TIFF files).

Maximum Entropy Fitting package

Last changed: 3 years 35 weeks ago

This is Maximum Entropy Package for solving problems which can be written as linear equation: I = G f, where I is measured signal, G is response matrix and f is a model distribution. It has been used for interpretation of a size distribution from small-angle scattering data, which involves the inversion of an integral equation for which there is no exact solution. It can likely be used for number of similar problems.

RatioImg

Last changed: 4 years 12 weeks ago

The RatioImg procedures are a set of Igor procedure files which provide convenient data loading, browsing, annotation, and measurement of ratiometric imaging experiments. They were written in 1999 by Howard Rodstein at WaveMetrics and Mark N. Rand at the Department of Neurology, University of Washington, Seattle using Igor Pro 3.1. Minor updates were made in 2007 to work with Igor Pro 6.

Size Distribution Fitting (lognormal) - Wdie-Range Particle Sizer (WPS) Data Processing

Last changed: 1 week 11 hours ago

This igor procedure is to handle the airborne particle size distribution data measured using Wdie-Range Particle Sizer (WPS), since the original software provided along with the instrument is not very user-friendly.

Starting with a neatly organized panel, all functions are simple and straightforward:
- Load raw data with a single click;
- Automatically obtain major parameters (RH, temperature) and calculate the hourly average; (daily or monthly average will be added in future release)
- Graphing (size distribution, color-coded by number conc.);

Time-Frequency Toolkit

Last changed: 3 years 30 weeks ago

Graphical user interface for time-frequency decomposition of a signal. Future development will include multiple GUIs for time series manipulation and analysis - hence the "Toolkit" designation.
