In addition, if 'gamma_only' is set to 0, then the optinoal k-point sampling index appears with the k-point index attached to the electronic wave function file names. Finally, if [out_app_flag](#out_app_flag) is set to false, the file name contains the optinal 'g' index for each ionic step that may have different geometries, and if [out_app_flag](#out_app_flag) is set to true, the wave functions accumulate during ionic steps.
