• The "boundary lines" look like crop marks that seem to come from the document class. Check the documentation for class bioinfo. – Heiko Oberdiek Jan 11 '17 at 4:47

The bioinfo class you are using provides the two options

• crop
• nocrop

to specify whether you want the crop marks or not. To specify nocrop, i.e. no crop marks, change the first line to

\documentclass[nocrop]{bioinfo}


similarly, to enable the crop marks explicitly, use

\documentclass[crop]{bioinfo}
