I would like to know if there is an automized or fast way to numerically derivate a large number of tab-delimited files (derived from the program kaleidagraph) and to automatically extract some key information from it?
It is a longitudinal growth study and i'm currently testing some non-parametric models. I have a tab delimited file with time in column 1 and size in column 2.
I wonder if there is a program that for every file can give me the second derivate numerically (that would be column 3) and the following parameters. - the maximum growth obtained (end of the curve) - the time T2 when velocity V2 is maximum and the corresponding velocity and size - the time T1 when velocity is minimum and T1
Since i have over a 1000 files and more i wondered if some tool or program could do the trick for me.
Thanks in advance
