It is actually the 1st letter after the end of the element in the array of arrays that precedes the "wanted" one (i.e. PF03797 in this case).
I had:
0 [ PF12951 421 455 ], 
1 [ PF03797 822 1073 ], 
2 [ PF12951 515 547 ],

, so, I need the range between the end of whatever is before PF03797 until the beginning of whatever is after PF03797 (in this case there is nothing, since both PF12951 finish before the position 822 that PF03797 starts).
