Hello,

We are trying to run Squeakr on environmental metagenomic datasets.
It is run on a node having 256 GB RAM, and 128 cores.

Squeakr was run on the samples whose number of estimated kmers is given here https://github.com/pierrepeterlongo/kmtricks_benchmarks/tree/master/tara-metag-bacterial/data/estimated_kmer_counts_metaG_bact

The command is

squeakr count -k 20 -c 1 -s ${log_slots} -o output_${sample}/res ${input_files} -t 128;

log_slots value is in [34,36], depending on the datasets.
output_${sample} directory is created before the run.

squeakr prints Reading from the fastq file and inserting in the CQF. and then stops indicating a seg fault. It lasts from 5 minutes to 20 minutes.

Max memory usage ranges between 2GB and 86GB depending on the sets.

Could this be related to this issue #32 ?

Any other idea ?

Thanks!
Pierre
