MD run error

[marci]

Dear ..

as the error message clearly states
*** Zero degrees of freedom. Nothing to thermalize! ***

your structure has 288 atoms, and you want 287 of them to be fixed. 
Then you are left with 3 coordinates, by subtracting the three degrees of 
freedom for translational motion, 
you are left with zero DoF..... the thermostat has nothing to thermalize
