ERROR: COPY <Table Name> FROM <file>

Dear group,
I am trying to upload a file into a table using COPY
command.

My table:

exp_id exp_X exp_y exp_std exp_npix

My file:
CellHeader=X Y MEAN STDV NPIXELS

My sql statement:
create table EXPERIMENT
(
exp_id serial not null,
exp_name varchar(32) not null,
con_id serial references
contacts(con_id),
exp_type varchar(32) not null,
exp_desc varchar(64),
exp_pmid integer not null,
exp_rawdata_url varchar(32),
constraint experiment_pk primary
key(exp_id)
);

My copy statement:

marray2=> COPY affy_exp from
'/home/speri/temp/postgres/marray2/tm.cel';
ERROR: must be superuser to COPY to or from a file
HINT: Anyone can COPY to stdout or from stdin. psql's
\copy command also works for anyone.
marray2=>

Could any help me whats going wrong with this COPY and
\copy (two different commands).

Thanks

Kumar
