Every once in a while I touch this code and find that noodles has gone up 20 versions 😁 This time, I'm going from noodles 0.49 / noodles-bam 0.43 to 0.65 / 0.56 respectively. I was able to get my code running by looking through the changelog--I just needed to not read/write reference sequences, and change how I parsed the tag I need. Now my code runs, but the output appears to be invalid for some reason.
Trying samtools view on the result gets me [E::sam_format1_append] Corrupted aux data for read [read name]. I'm not sure how to diagnose what's wrong here. If I try to read the output with pysam it gives me KeyError: "unknown type '71'" in the tags, so I'm guessing the tags are being mangled somehow.
I'm just filtering a BAM file based on a tag (an array of two uint16) and separating the reads into different output BAMs. I use async readers and writers to speed things up.
Code example
info!("Reading from {}", input_bam.display());let(mut reader, header) = make_reader(&input_bam).await?;
...let mut writers = make_writers(&header, output_bams).await?;debug!("Reading records from BAM");letmut records = reader.records();whileletSome(record) = records.try_next().await? {ifletSome(Ok(Value::Array(Array::UInt16(bc_val)))) = record.data().get(&BC){let bc_val:Vec<_> = bc_val.iter().filter_map(|s| s.ok()).collect();if bc_val.len() != 2{debug!("bc array with length {}, that's weird!", bc_val.len());}else{ifletSome(p) = barcode_map.get(&bc_val){ifletSome(writer) = writers.get_mut(p){
writer.write_record(&header,&record).await?;}}}}}for writer in writers.values_mut(){
writer.shutdown().await?;}
That code is slightly modified from before to extract the tag correctly, but not much has changed. What did I miss here?

It's a bug, sorry! There was a typo in how value counts were calculated. It affects noodles 0.61.0-0.65.0/noodles-bam 0.53.0-0.56.0 when using BAM format records (bam::Record) that have data array fields.
This is now fixed in noodles 0.66.0/noodles-bam 0.57.0. Thanks for reporting!
