Can deletedgenomes or subtree be recovered?

[Baohua-Chen]

Hi,
I have deleted some genomes using halRemoveSubtree from a hal file. I didn't realize that it will change the input file directly rather than generate a new file at the time.
I noticed that the new file have similar size to the original one. So, Is it posible to recover the deleted genomes or subtree?

Thanks,

Chen

I don't think so, unfortunately. The information is still in the file in theory, but it's been unlinked in a way that I don't think HAL can recover it from.
