unable to decode

[skyup259]

i have done creating a parity matrix ,encoding message and transmission and i unable to do decoding.
i am using below command to do decode.
decode -f -T p.pchk pencode1.txt pdecode.txt bsc enum-block p.gen

but it showing error
Usage:
decode [ -f ] [ -t | -T ] pchk-file received-file decoded-file [ bp-file ] channel method
Channel: bsc error-probability | awgn standard-deviation | awln width
Method: enum-block gen-file | enum-bit gen-file | prprp [-]max-iterations

where
p.pchk -> pchk-file e
pencod1.txt ->received-file
pdecode.txt-> decoded-file
bsc -> channel
enum-block -> method and p.gen is generation file.
