I suffer the pain to compile the old fortran source code using gfortran. I did not have many experience to do this, so please help me to correct the source code based on the error message.
disturbance.f:1416.31:
1505 format ( I7, E12.3, < npftu>E10.3 )
Error: Unexpected element '<' in format string at (1)
please note that there is no space between npftu and < >.
