[maker-devel] scaffolds missing from master_datastore_index.log and all.gff files

[Carson Holt]

If running multiple jobs of MAEKR at the same time, you can hot a race condition where once MAKER run keeps another from making the correct entry into the datastore log.

You can delete the log and then run ‘maker -dsindex’ to rebuild it which a single maker process (takes less than 5 minutes ).

I have noticed that the number of contigs (aka scaffolds) differs among the different rounds of annotations I have done in MAKER, ranging from 12024 to 12027 scaffolds. These counts were obtained with the SOBAcl tool to count the number of contigs from each all.gff file generated by the gff3_merge script included in MAKER.

This scaffold (LG08_unordered_scaffold_90) should be in the gff3 as it had some repeat masking done on it as indicated by the query.masked.fasta file for this scaffold in its theVoid directory.
