RodSim Home Page

---

‘RodSim’ comprises a set of Matlab routines for solving the differential equations of phototransduction given in our paper:

Nikonov, S., Lamb, T.D. & Pugh, E.N. Jr. (2000).  The role of steady phosphodiesterase activity in the kinetics and sensitivity of the light-adapted salamander rod photoresponse.  Journal of General Physiology 116, 795-824.

Condition:  The routines are provided on the understanding that their use will be acknowledged, by citation of ‘RodSim’ and the paper above.

Requirements:  MatLab (The MathWorks, Inc.) version 5.2, 5.3 or 6.0.  Display of 800 × 600 or higher.  RodSim was developed under Windows, and has been tested briefly on a Mac.

Preview:  Click here to view a JPEG (63 kB) of the RodSim control panel.

Download:  Click on either of the following to download v3.30 of RodSim:

• Self-extracting 32-bit PKSFX Windows file (‘RodSim_Release_330_Zip.EXE’, 192 kB) -- Recommended
• Regular zipped file (‘RodSim_Release_330.ZIP’, 64 kB) -- Ensure you use a 32-bit extracter or you will lose long file names.

Extract:  Extract the files to a directory such as ‘C:\RodSim’, and then ensure that this directory is pathed within Matlab.

Running:  Start Matlab, and give the command ‘RodSim’.

Figure 14:  To re-create Figure 14 from the paper, start Matlab, and give the command ‘Fig_14’.  This runs RodSim offline, using the parameters for all the traces in Fig. 14, and then plots the individual panels.

Brief description:  A brief description of RodSim is provided in the Help file.

Differential equations:  The full set of differential equations is given in the Appendices of our paper.
