EXTRACTOR is a program that extracts data from formatted and labeled MODFLOW head or drawdown files or from MODFLOW-GWT concentration or velocity files. The user specifies the number of rows, columns, and layers in the target data file, the desired time step or move number, and the range of rows, columns, and layers for which data should be extracted and written to a new text file. The new text file can then be imported into other data-analysis programs.
