SVA annotation refinement module output "-1" meaning

[mechealeth]

Hi,

I would like annotated the whole genome SVA-F and to get chromosome coordinate of HEX/Alu-like/ VNTR/SINE-R of each locus of SVA-F. I tried to using SVA annotation refinement module and I get the result as following:

I am not very clear about the output, especially Alu_like and SINE_R column with value "-1" . It would be really nice if you can help me understand this reseults

many thanks
