P contigs of length 0

[dcopetti]

Hello, I realized that after Falcon Unzip I have some p-contigs of length 0 (there is an empty line), while there are haplotigs for that sequence. Counting the length:

000870F [empty]
000870F_001    15026
000870F_002    152914
000870F_003    63913

Looking in the 3-unzip folder, ctg 870F has phased reads:

0 000870F 1 1 10 36 m161228_035316_42219_c101154552550000001823268507191790_s1_p0/103469/10714_36102

but no lines in all_p_ctg_edges

the 3-unzip/0-phasing/000870F folder contains:

I have 13 contigs like this in this assembly, and two in another, always made with the Unzip step. Is there a way to recover those contigs? Thanks, Dario
