Joystick XOP

Last changed: 1 day 5 hours ago

This XOP allows Igor to read and control the inputs and outputs from and to a force feedback joystick. These are relatively inexpensive consumer devices used mainly for playing games, I presume, but can be useful elsewhere (atomic force microscopy?), as they are for my purposes, where a monkey uses the joystick. In general, the idea is to provide a haptic interface within Igor. Of course, there may be a market for Igor gaming. :-)

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

Last changed: 3 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.

GenCurvefit

Last changed: 7 weeks 21 hours 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.

ZIP - inflating and deflating (.z and .gz format) strings using zlib

Last changed: 9 weeks 17 hours ago

This XOP will inflate and deflate strings that contain information encoded in .z and .gz formats. It will not handle .zip or multifile zip files. The encoding is done in .gz format.

It is based on the free zlib library.

Useage:

string test = "0123456789"
string test2 = zipencode(test)
string test3 = zipdecode(test2)
print test3

or

variable fileID
open/r fileID      //open a .gz file
fStatus fileID    //get the length of the file in bytes
string inData = "" 
inData = padstring(indata,V_logEOF,0)   //make the indata string as long as the fileitself

Procedure File Manager Panel

Last changed: 17 weeks 21 hours ago

This package displays a panel with a checkbox list to select procedure file(s) for loading/unloading and checkboxes to set certain coding-specific parameters. It might be a useful tool for programmers who are coding on different procedure files or for users who wish to load/unload different procedure files in an effective manner.

NeuroAcquire

Last changed: 21 weeks 1 day ago

NeuroAcquire allows one to collect physiology and imaging data in a single instance of IGOR. Often, physiology and image acquisition are performed by different third party packages, which can complicate the timing and triggering of data collection. Our hope is that NeuroAcquire simplifies the coordinated acquisition of both types of data by having all controls under one roof. You will need an ITC18 DAQ board and a SIDX-supported CCD camera to use this program. Future versions may support other DAQ boards.

Maximum Entropy Fitting package

Last changed: 23 weeks 4 days 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.
