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

Last changed: 1 week 10 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.);

GenCurvefit

Last changed: 2 weeks 2 days ago

GenCurvefit uses differential evolution (genetic optimisation), with a user defined fit function, to fit data with up to 50 independent variables. The technique is extremely good at finding global minima in Chi^2, even with poor starting guesses.

Expt Procedures

Last changed: 8 weeks 1 day ago

Template with an experiment file and several procedure files to help simplify data acquisition and management in Igor Pro. Includes generic data-taking routines, a convention for identifying data with unique serial numbers, procedure files to simplify data acquisition (see "DAQ Procedures" Project*) with GPIB, NIDAQ, serial port, and VISA, and procedure files to work with a few common SRS lockin amplifiers and Tektronix oscilloscopes. Each file contains its own documentation, and the experiment file contains a "GettingStarted" notebook.

DAQ Procedures

Last changed: 9 weeks 6 days ago

Procedure files to help simplify data acquisition (DAQ) in Igor Pro. Includes separate files for GPIB, NIDAQmx, traditional NIDAQ, serial port, and VISA. Each file contains its own documentation.

SpAcAn: Spontaneous Activity Analysis

Last changed: 18 weeks 7 hours ago

SpAcAn (Spontaneous Activity Analysis) is a collection if IGOR Pro functions for the detection and analysis of spontaneously occuring (non-triggered) events in electrophysiological recordings. SpAcAn was originally designed to facilitate the analysis of spontaneous synaptic activity in whole-cell recordings, but has also been used successfully to detect and analyze spikes or rapid changes in fluorescence.

ColorScaleSliders

Last changed: 18 weeks 3 days ago

ColorScaleSliders includes a single procedure file that lets you adjust the color scaling of false-color image plots using sliders. By combining smooth adjustments with immediate feedback, this helps you optimize the appearance of false-color plots, and allows you to find fine details.

string test2 = zipencode(test)
string test3 = zipdecode(test2)

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.

XOP function stub generator

Last changed: 42 weeks 2 days ago

From a specially crafted C header file, this Perl script can generate all necessary (resource file, header, and function) stubs for creating a XOP.
See the file example-header.h for an example input file, the output is in the files functionBodys.cpp, functionBodys.h, resourceFile.rc.
Requirements: A recent version of Perl and ctags from http://ctags.sourceforge.net/.
Call the script as ./xop-stub-generator.pl example-header.h.
