kmer_usage error

[slhogle]

Hi,

I'm getting an exceptions.AttributeError when using comparem kmer_usage. The same error occurs when supplying a genome list text file or a directory. However, aa_usage, codon_usage, stop_usage, lgt_di, and lgt_codon all work without error.

thanks in advance for any help, shane

Same error here. CompareM v. 0.0.23, macOS 10.13.3

[sarah872]

Same here on CentOS!

[johanneswerner]

Same error on Ubuntu 16.04.2 LTS with CompareM v. 0.0.23

Below is the function from the file kmer_usage.py

    def _consumer(self, produced_data, consumer_data):
        """Consume results from producer processes.

         Parameters
        ----------
        produced_data : list -> [genome_id, kmer_usage]
            Unique id of a genome followed by a dictionary
            indicating its kmer usage.
        consumer_data : namedtuple
            Set of kmers observed across all genomes (kmer_set),
            along with the kmer usage of each genome (genome_kmer_usage).

        Returns
        -------
        consumer_data
            The consumer data structure or None must be returned
        """

        if consumer_data == None:
            # setup data to be returned by consumer
            ConsumerData = namedtuple('ConsumerData', 'kmer_set genome_kmer_usage')
            consumer_data = ConsumerData(set(), dict())

        genome_id, kmer_usage = produced_data

        consumer_data.kmer_set.update(kmer_usage.keys()) # <- here it fails
        consumer_data.genome_kmer_usage[genome_id] = kmer_usage

        return consumer_data

I understand why it fails but how could this have worked in the first place? lists have per definition no key attribute.

[donovan-h-parks]

Hello. kmer_usage is suppose to be a dictionary based on my own documentation. :)

Is there an actual bug here (i.e., produced_data) is not in the expected format?

[johanneswerner]

I would assume so because several people had the same problem. I can provide example data if that would be helpful.

[lalalagartija]

Same problem here. Has someone found the reason for this ?

[donovan-h-parks]

Addressed in forthcoming Py3 release.
