text: user4595: Where I can find a database or tool to give me the target genes of PIWI (piRNAs) in human?
  I found one but works for worm like piRTarBase
  There are a lot for miRNAs around but not for piRNAs
  
  user2108: Update
  It does indeed appear that while piRBase etc. have human piRNAs, they do not have target information.
  Looking at related questions, recommendations are made to map piRNA sequences to the genome to find the targets. One tool recommended is PiPipes, which might assume read input but otherwise might give some ideas.
  Original answer
  piRBase has this. See "target mRNA" field.
