hi,
did you check the BAM header with samtools view -H <YOUR_BAM>
? My naive guess would be that the FASTA sequence you are using with --genome is slightly different (at least in terms of sequence names) from the one used to generate the Bowtie2 index.
I've run into the same exception in a rather peculiar corner case: my dataset has very low coverage of 2x (this is a part of a tools evaluation work package). With such low coverage it is conceivable that some of the contigs of the large plant genome got no reads at all.
In my case this is clearly a data issue, and not a Pilon issue 🙂 (Pilon could skip contigs without sequences, but I'd actually prefer to have an exception - like it is now - so that any problems are highlighted.)
Maybe the issue could be closed as neither of the reported cases point at any code problems in Pilon.
Hi,
I tried running java -jar /Users/emmannadi/pilon/pilon-1.23.jar --genome /Users/emmannadi/Documents/C_afrcana_download/CBS11016/Sequences/CBS11016_Unordered_spades.fasta --bam /Users/emmannadi/Documents/C_afrcana_download/CBS11016/Bowtie2/SC5314.bam --threads 30 --fix all --output /Users/emmannadi/Documents/C_afrcana_download/CBS11016/Bowtie2

What can I bet getting wrong
