I'm looking for a program to perform a particular function and I'm hoping
one of you can suggest a source.
I have a program called TableCurve 2D which has numerous functions for
analyzing numerical data. It has an elegant graphical interface for user
interaction. My primary use of it is Fourier filtering or smoothing. It
presents a histogram of the spectral composition of your data and allows you
to delete any components you wish. I use it almost exclusively as a
low-pass filter. One very important characteristic of the program is that
for EVERY data point in the input there is a corresponding data point in the
output - in other words, if N represents the value of X at the last data
point in the input, the output also has a point at X=N. (I realize that the
Y value at X=N may change as additional points are added beyond N, but I can
live with that.)
Here's my problem: The user interface is elegant, but strictly manual. I
need to be able to pass 40, 100, or more files through such a filter (same
frequency cutoff for all) and it is simply too tedious and time-consuming to
handle each one manually.
What I need is a program which has the above filtering capability but which
either
(1) has some kind of macro capability permitting me to automate the process
for many files (must be able to specify a list of input and output file
names and the cutoff frequency or wavelength), or
(2) can be invoked from the command prompt with input and output file names
and the cutoff value specified on the command line.
I've checked with SPSS, the firm that produces TableCurve, and they can't
help me. Any suggestions where I might find such a program?
Regards,
Carroll S.
