Curve Fitter

The Internet is filled with all sort of applications and programs that you could use in order to make your job easier. One of them is Curve Fitter.
It's a program designed to fit microbial growth curves, in particular those generated by periodically reading OD measurements of cultures growing in microtiter plates. It sports a lightweight and clean graphical interface with many nice tools at hand.

Sleek and intuitive graphical interface

The application doesn't take long to install and it doesn't come with a complicated setup that you would need to complete before you can actually use it. It sports a clean and intuitive graphical interface with many nice tools at hand.
Curve Fitter is a program designed to fit microbial growth curves, in particular those generated by periodically reading OD measurements of cultures growing in microtiter plates.

It provides methods to visualize the data and to fit different growth models and to visualize those fits.  The program is composed of two parts.  The first is a graphical user interface (GUI) program which interactively displays the data, different model fits and allows one to inspect these things.
The program has a number of features to plot and display data, as well as to show various diagnostic plots and groupings by different treatments. The second component of the program is a scripting environment console which allows one to rapidly process large amounts of data and generate custom plots using the tools in Curve Fitter.

More features and tools

It comes with a sensitivity tab that displays for each growth curve how the estimated growth rate changes as the low end and high end of the fitted range varies.  The value at a given position is the instantaneous growth rate obtained by fitting from all values from the start of the range defined on the y axis to the end of the range defined on the x axis.
All in all, Curve Fitter is a very useful program designed to fit microbial growth curves, in particular those generated by periodically reading OD measurements of cultures growing in microtiter plates.
