(note: This command appears to be broken. BGG, 7/2012)
getpch will retrieve a pitch value from an LPC analysis file, possibly created by the MiXViews program. "lpc_data_file" is a string with the name of the file. This may be an absolute or relative pathname to the LPC analysis file. frame# is the analysis frame to be retrieved.
pval = getpch("/some/LPC/analysis_file.lpc", 268)
