i am using l297 and l298 based stepper drive. i got 6 wire unipolar stepper motor, my doubt is that can i convert the unipolar to bipolar by ignoring the two center taped conman pins. does the motor run without any problem?
 

Yes, but keep in mind that the characteristics change since you've basically got two inductances in series when you run in bipolar.
