Narrative:

On climb out from dfw on the nobly departure; the aircraft deviated north of course about 15-20 miles. Apparently on loading the FMS; the departure was incorrectly loaded or on climb out it was changed. After nobly; the aircraft went direct to lit VOR as the two points before were deleted. On preflight only the first 3 or so points were checked for the RNAV departure. After we passed nobly; we failed to notice the rest of the departure was correctly in the FMS until center called and had us turn right 15 degrees.supplemental information from acn 684505: evidently the lit transition had not been selected by the captain when he programmed the FMC. I had checked the route before departure and it was accurate however I didn't get the chance to check the legs due to preflight activities distracting me.
