              ED50plus     v1.0      April 2000
*****************************************************************

ED50plus is a tool for pharmacological analysis. This is a
worksheet for MS Excel which allows you to create and analyze
dose-response curves. Some of its features are:
- Construction of up to 10 curves with up to 30 points each.
- Manipulation of X and Y axis (including probit-transformation)
- Visualization of each curve.
- Calculation of up to 3 intercepts on each curve, thus allowing
  you to obtain common parameters as ED50, IC50, LD50, PD20, etc.
- Averaging of the results,   

I developed this worksheet in MS Excel 97 (TM). However, this 
worksheet must also have good performance in any Excel version
(4.0 or higher).

It is strongly recommended to extensively assess the performance
of this worksheet before rely on it. NEITHER I NOR THE INSTITUTO
NACIONAL DE ENFERMEDADES RESPIRATORIAS ASSUME ANY RESPONSABILITY
FOR POTENTIAL ERRORS ON THIS WORKSHEET.

This worksheet is FREEWARE, so you can freely distribute it to
your colleagues, as long as it is not modified in any way.
