Hello all,
I have experimental data that is stored in a number of files. I've
been importing the files (as tables) into Mathematica one-by-one, and
working on them like so:
rawdata=Import["C:\\filename.ASC", "Table"];
croppedcorrelation=Take[rawdata,{75,185}];
statistics=NonlinearRegress[croppedcorrelation, math_here...]
then painstakingly picking out the relevant statistical parameter from
each file, collecting them all, and later plotting them. What I'd
really like to do is import an entire directory's worth of these files
(each file is a different time point), do the same statistical thing to
each file, save the relevant parameters from each file in a table form
and then plot the whole shebang.
One of the problems is that I don't know ahead of time how many .ASC
files are in the directory, so I need to set up the For loop (or
whatever structure) to account for that. I tried using FileNames[] to
get the list of files, assigning them to an array, then using Import[]
on each of those array elements. It didn't work.
Does anyone have any suggestions?
Thanks!
Dan
