I am trying to make a user defined quadratic equation for protein ligand binding. The compile always fails for some unknown reason. Here is the equation, parameters, and test data. Please can anyone help me?
y = Vmax * (((Et + x + KD) - sqrt((Et + x + KD)^2 - 4*Et*x))/(2*Et)
Parameters:
Vmax = 1.1
KD = 0.000003
Et = 0.00003
Et is a constant and can be fixed. KD is known from another technique so it should be very close. Vmax is an approximation and could be off a little.
Test data:
x space y
0.00006 space 1
0.00003 space 0.84
0.0000225 space 0.7
0.000015 space 0.54
0.0000075 space 0.29
0 space 0
Thank you,
Adam |

Hi Adam,
Utilizing "Edit: Go To Matching Brace" menu in CodeBuilder, I found a mismatched parenthesis of the first '(' as extra.
