Abstract: We investigate gradient of magnetic field across neutral lines (NLs), and compare their properties for NLs with and without the chromospheric filaments. Our results show that there is a range of preferred magnetic field gradients where the filament formation is enhanced. On the other hand, a horizontal gradient of magnetic field across a NL alone does not appear to be a single factor that determines if a filament will form (or not) in a given location.<br />Comment: 11 pages, 8 figures
