INCLUDEIncludes an external input file, similar to #include in C preprocessor. More details. Show included file FILEfile to be included=./MuellerBrown-Potential.dat
# INCLUDE FILE=./MuellerBrown-Potential.dat
# vim:ft=plumedEnables syntax highlighting for PLUMED files in vim. See here for more details.
