SCIP cannot read my input

Question

I'm trying to use the SCIP solver (http://scip.zib.de/). My input (1.lp) is in lpsolve format. It looks like this:

max:  +2 x_0_0;
 +x_0_0 <= 1;
 +x_0_0 <= 1;
 -3x_0_0 <= 0;
0 <= x_0_0 <= 1;
int x_0_0;

I run SCIP like this:

"c:\Program Files\SCIP\scip.exe" -f 1.lp -l 1.lp.out

However, SCIP generates this output:

user parameter file <scip.set> not found - using default parameters

  input:

error reading file <[...]1.lp>

I guess that means it is choking on a whitespace... What am I doing wrong?

EDIT:

See my answer for details. After giving the input in CPLEX format, everything works fine.

Answer 1

The answer is that SCIP apparently cannot read lpsolve input files. The LP format they are referring to in this overview of readable file formats is in fact the CPLEX LP format.
