Perl scripts for data analysis

These scripts give target-correct identification rates for various conditions, for all subjects. Layout is one condition per column, one subject per line. The set of conditions differs between scripts. You most certainly want to make your own.
This script takes data from the previous scripts and calculates mean and standard deviation over subjects: This one simply transposes (tab-spaced columns <--> cr-spaced lines):
Example (supposing system is UNIX, and data are in directory 'data/'):
  i4 data/*  | msd | transp
reports the mean and standard deviation (over subjects) of identification rate for all four dF0 conditions, averaged over vowel pair and level (main effect of dF0). The data are transposed to obtain one condition per line.
