Hi,

I am using ONT R10.4.1 provided by EPI2ME ( https://labs.epi2me.io/askenazi-kit14-2022-12/ ) and testing with whatshap. However, I encountered an error during the process. How can I resolve it? Here are the commands I used.

whatshap --version
1.7
whatshap phase --ignore-read-groups --indels \
-r GCA_000001405.15_GRCh38_no_alt_analysis_set.fa \
hg002.wf_snp.vcf.gz \
hg002.sup.60x.bam \
-o whatshap_hg02_60x.vcf
bgzip -c whatshap_hg02_60x.vcf > whatshap_hg02_60x.vcf.gz
tabix -p vcf whatshap_hg02_60x.vcf.gz
whatshap haplotag --ignore-read-groups  \
whatshap_hg02_60x.vcf.gz hg002.sup.60x.bam \
-r GCA_000001405.15_GRCh38_no_alt_analysis_set.fa \
-o hg002.sup.60x.whatshap.haplotag.bam

samtools index -@ 24 hg002.sup.60x.whatshap.haplotag.bam
whatshap stats --gtf whatshap_hg02_60x.gtf whatshap_hg02_60x.vcf.gz
~/methphaser/meth_phaser_parallel \
-b hg002.sup.60x.whatshap.haplotag.bam \
-r GCA_000001405.15_GRCh38_no_alt_analysis_set.fa \
-g whatshap_hg02_60x.gtf \
-vc whatshap_hg02_60x.vcf.gz  \
