IgorCL is an external operation for Igor Pro that allows you to perform calculations on your computer's CPU or GPU using OpenCL. OpenCL is a software framework that provides a uniform way to perform computation on heterogeneous devices. The authoritative source on OpenCL is the official website, http://www.khronos.org/opencl/, and particularly the OpenCL specification.

Syntax Highlightning in VIM

Screenshot of gvim under linux

Based on the work of Peter Li, http://www.hcs.harvard.edu/~pli/code/#vim, I completely revised the syntax highlighting for Igor Pro procedures in Vim.

Install into a folder read by gvim and add filetype detection code to vimrc

" add filetype detection for Igor Pro procedure files
let igorpro_default_colors = 1
au BufNewFile,BufRead *.ipf set filetype=igorpro

The variable igorpro_default_colors controls if the default colors like in Igor Pro are forced or the user settings should be honoured instead. By default the user settings are honoured.

Tektronix Oscilloscope Waveform Loader

Downloaded 154 times
Average rating
(0 votes)

This is an attempt at a fairly universal loader for the dizzying array of Tektronix oscilloscope binary waveform file types (.wfm and .isf). It imports file types LLWFM, WFM#001 to #003 (.wfm files) and WFMPRE (.isf) from a wide range of Tektronix models. It can handle multi-frame waveforms generated by fast-framing scopes as well, with time stamps. It does not support pixel map types.

The core of this utility is the function LoadTekWfm, which does the heavy lifting. It's designed to be called from other macros and functions that customize the user interface.

twoPhoton scanning laser microscopy control

Code for using Igor Pro with NIDAQ toolkit and National Instruments data acquisition boards (PCI-6110 or similar for imaging plus optionally a PCI-6036 or similar for electrophysiology traces) to drive a scanning laser microscope system, as for confocal or 2-photon microscopy. Igor Pro/NIDAQ drives the galvanometers that direct the beam, and collects the data. Can also control moving the microscope stage around, as for controlling focus to make z-stacks. Includes some code for analysis of images/image stacks.

Schroedinger_Solver

Downloaded 169 times
Average rating
(0 votes)

Schroedinger_SOLVER is an IGOR PRO procedure that integrates numerically the Schroedinger equation with the NUMEROV method to obtain the time-independent -or stationary- solutions, for any given 1-D potential. The solver assumes boundary conditions in which the wave function is zero at both extremes of the space domain (coordinate x). In practice this means that the potential is assumed to be infinite at xmin and xmax. Therefore, for the moment the code is not prepared for solving, for example, the Coulomb potential.

Igor preview generator for OS X

Preview viewer window

This project will automatically create a preview of a saved Igor experiment by compiling its available windows into a notebook and saving the notebook in a central location and keep track of them with a UUID that matches a generated UUID string stored in the experiment.

The script will list the pxp files in the specified folder (instead of the notebook previews), and when you select one it will access the UUID stored in the pxp and match it to the appropriate preview file (or display "No Preview Available" if a preview has not yet been generated).

Preview panel: Save (top) and View (btm) tabs

The aim of this project is to aid the Igor Pro user in selecting one among many saved experiments. The method is to create a formatted notebook containing currently visible graphs in an open experiment. The notebook is saved under the same name and directory as the experiment. Saved notebooks can be quickly viewed through a panel containing a simple method of selecting a disk path and displaying the names of notebooks residing in that path in a list box. Contents of the notebook are displayed in a notebook subwindow on that panel when the user clicks on a item in the listbox.

LS_analysis_panel.png

A procedure for generating kinetic profiles from analysis of intensity values from confocal line scans.
Sequential line scans are imported into 2D waves from either TIFF or Zeiss LSM* files.

Analysis options include:

  • choice of statistical test run on line scan data
  • ability to set inter-line scan-interval
  • stat values output to data table
  • creation of a graph and curve fit options

Running "Line Scan Analysis" from the Macros menu creates a panel (see screenshot).

Igor Sequencer Panel

Igor Sequencer controls an Arduino device to produce sequences of output pulses in a user-defined sequence. It provides low cost control of up to 12 outputs in two banks of 6 pins with sub-millisecond accuracy. Sequences are programmed through a GUI and they can be saved and loaded for quick recall.

You will need an Arduino Uno or Mega (it will probably work with other Arduino models as well). A sketch is provided which contains the code to install on the Arduino. A manual describing installation and operation is also available for download.

// Function ProgressMeter routines
//*****************************************************************
// Routines to create, update and destroy a little progress meter. This uses
// igor drawing commands in a panel. Data is normalized to a 0 to 100 unit
// scale and meter is updated every 5 units (20 increments).
// Truncates name to 40 characters and ensures that name is igor legal. Always
// use return value (string) from ProgressMeterCreate as MeterName parameter

This set of files allows you to get syntax highlighting in gedit (http://en.wikipedia.org/wiki/Gedit) or meld (http://en.wikipedia.org/wiki/Meld_%28software%29). These editors are crossplatform (windows, mac, linux) and open source.
This allows to compensate for some missing features of the native igor editor, namely:

  • autocompletion
  • line numbering
  • automated bracket completion
  • automatic indentation
  • bookmarks
  • code snippets
  • Line wraping when printing
  • case change

Channel Rhodopsin Mapper (ChRMapper) is a package written for Igor Pro 6.1 or higher for making photoactivation maps in motor cortex expressing channel rhodopsin (Ayling et al., Nat Methods. 2009 Mar;6(3):219-24; http://www.ncbi.nlm.nih.gov/pubmed/19219033).
ChRMapper requires:

  1. Data acquisition board from National Instruments
  2. NIDAQmx XOP (http://www.wavemetrics.com/products/nidaqtools/nidaqtools.htm)
  3. Computer-controllable stage (usually serial port with VDT2).
  4. Laser plus associated optics to focus it on the sample (see paper for details).

The Igor Pro procedure file syntax is not supported by doxygen.
The easiest way to support it, is to write an input filter for doxygen.
This project here is a proof of concept implementation in AWK of an filter which translates procedure files into C-ish output.

Requires GNU AWK.

Supported Features
  • Functions, including parameter type resolution and call-by-reference recognition
  • Constants
Workflow
  1. Comment procedure files using doxygen commands
  2. Tweak doxygen config file and define
