[SIESTA-L] Error :Usage: pdos filename

[郭振东]

Hello everyone,
  When I use the siesta to calculate the DOS, I always meet such error : Usage: 
pdos filename.
 $   ./pdosxmlF < PDOS.INPUT > FDOS.dat
  Usage: pdos filename
I checked the file  FDOS.dat, i found the file is blank.Would you like to give 
me some help ? I will be very thankful.
