Hi, I am trying to run prune_graph but I keep getting this error:

thread 'main' panicked at src/graph.rs:83:42:
cannot convert weight to float32: ParseFloatError { kind: Invalid }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

the command I used was

./target/release/prune_graph --header --in /home/mar/Documents/BonoboData/Inbreeding/Kokolopori_1x_downsampled_LD_newhead_bis.tsv --weight-field "r2" --weight-filter "dist <= 50000 && r2 >= 0.5" --out /home/mar/Documents/BonoboData/Inbreeding/Kokolopori_1x_downsampled_LD_unlinked.pos` and the input file is as seen below (lines 1-24).

Would you be able to help me with this issue? I thought it might be the header but it doesn't seem to be the problem. Thank you in advance

The error message means that there is a weight (r2) with a value that cannot be converted to a float32

Is that your full file? If not, are there any values on the column r2 that might be invalid?

Hello, in the end we managed to run the python script from ngsLD to do the pruning and it worked! Thanks anyway :)

If you have time, it would still be nice to know what was that could not be converted to a float32. It is just so I can fix it and avoid future issues with other users.
