[Help-glpk] WIN GLPK 4.57 error of solving .mps or .lp format linear programming models

[usa usa]

Hi,

I am trying to use Win GLPK 4.57 (http://sourceforge.net/projects/winglpk/) to solve some large-sized linear programming models from Win 7 command line.

    glpsol.exe --mps FileName

I have downloaded some LP problems from

http://www.cuter.rl.ac.uk/Problems/netlib.html

But, when I sovled it with GLPK, I got error:  missing indicator record.

I am not sure SIF format can be read by GLPK.

and

http://plato.asu.edu/ftp/lptestset/network/

I got error: invalid indicator record

Could someone recommand some websites where I can find large sized LP models (.mps or .lp) format so that I can solve them with GLPK 4.57.

Any help would be appreciated.

Thanks
