This is duplicate with #258. Please do not open new tickets for the same issue!

Also, please understand we do not have the ressources do give everybody detailed support on simple issues. If you are a student, your supervisor should be your first address, and they should be able answer a question like this. As an exception, I have looked up in the source code file openouttraj.f90 what is written out (you could have done that as well). I think this should be self-explaining:

      open(unitouttraj,file=path(1)(1:length(1))//'trajectories.txt', &
      form='formatted',err=998)

      if (ldirect.eq.1) then
      write(unitouttraj,'(i8,1x,i6,1x,a)') ibdate,ibtime,'FLEXWRF  V3.0'
      else
      write(unitouttraj,'(i8,1x,i6,1x,a)') iedate,ietime,'FLEXWRF  V3.0'
      endif
      write(unitouttraj,*) method,lsubgrid,lconvection
      write(unitouttraj,*) numpoint
      do i=1,numpoint
       if (outgrid_option .eq. 0) then
         xp1=xpoint1(i)*dx+xmet0
         yp1=ypoint1(i)*dy+ymet0
         xp2=xpoint2(i)*dx+xmet0
         yp2=ypoint2(i)*dy+ymet0
        endif
       if (outgrid_option .eq. 1) then
          xtmp = xpoint1(i)*dx+xmet0
          ytmp = ypoint1(i)*dy+ymet0
          call xymeter_to_ll_wrf( xtmp, ytmp, xp1, yp1 )
          xtmp = xpoint2(i)*dx+xmet0
          ytmp = ypoint2(i)*dy+ymet0
          call xymeter_to_ll_wrf( xtmp, ytmp, xp2, yp2 )
        endif
!jdf    write(unitouttraj,*) ireleasestart(i),ireleaseend(i),
!jdf +  xp1,yp1,xp2,yp2,zpoint1(i),zpoint2(i),kindz(i),npart(i)
!jdf    write(unitouttraj,'(a)') compoint(i)(1:40)
        write(unitouttraj,*) ireleasestart(i),ireleaseend(i), &
        xp1,yp1,xp2,yp2,zpoint1(i),zpoint2(i),kindz(i),npart(i)
        write(unitouttraj,'(a20)') compoint(i)(1:20)
       enddo
