Narrative:
Pushed on time/taxied to runway 18R. Told to expect 10 min delay. Informed flight attendants and passenger. Cleared for takeoff. Ran before takeoff checklist and rang flight attendants. Commenced takeoff. First time to fly this departure (gandy 2). Calls for LNAV at 420 ft. Gandy is to the west. Was a little late selecting LNAV; about 700 ft. Initially the LNAV commanded left turn. I started turn to left to follow command bars but quickly realized this was incorrect; so I started turn reversal and programmed FMC for direct gandy. As we were going through about 1500 ft and almost on heading for gandy; tower came on frequency and said company flight number stop turn immediately and either said go direct gandy or gave a heading to gandy and told us to call tower when we got to our destination. Upon arrival; I paged our ATC manager; but ran out of time before he called back; so I called tower. Spoke with the supervisor line manager. He said there was no conflict and also said they had had numerous airliners do the same thing and in particular several company aircraft. He asked for my address; phone and certificate number and said internal paperwork had been started. Well; obviously we thought we had done everything correctly prior to takeoff. All I can think of is be sure you know which way the initial turn is and look at the map if you're in a -700.
