WARNING: Plugin 'LoF' went wrong: Can't locate object method "prepare" via package "false" (perhaps you forgot to load "false"?)

[xx3411]

Hello!
I'm running vep from the https://github.com/konradjk/loftee/tree/master branch,

${DIR}/vep -i /dt19/share/BC0001/Level3/20210715/vcf/S002_DNM_V4_7_filtered_noAS.1.3.2.siteonly.dn.vcf.gz
-o temp.vcf
--vcf --dir_cache ${DIR}/vep_database --cache --species homo_sapiens --assembly GRCh37
--fasta ${DIR}/vep_database/Homo_sapiens.GRCh37.dna.primary_assembly.fa
--force_overwrite
--offline
--plugin LoF,loftee_path:${DIR}/Plugins/loftee,human_ancestor_fa:${DIR}/Plugins/loftee/human_ancestor.fa.gz,phylocsf_data:${DIR}/Plugins/loftee/phylocsf_gerp.sql
--dir_plugins ${DIR}/Plugins/loftee

and I'm getting a lot of warnings like this one

WARNING: Plugin 'LoF' went wrong: Can't locate object method "prepare" via package "false" (perhaps you forgot to load "false"?) at /public/home/xx2019/software/ensembl-vep/Plugins/loftee/gerp_dist.pl line 129.

How can I solve this problem?

Hello I had the same problem as you, to solve it you have to download the sqlite "phylocsf_gerp.sql", you can downloaded from the link that readme provides in this github "The required SQL database (gzip) can be downloaded here."

Then you have to uncompress and finally, the argument that you have to include is conservation_file:/your/path/phylocsf_gerp.sql. Concretely near to human_ancestor_fa:${DIR}/Plugins/loftee/human_ancestor.fa.gz, something like this:

human_ancestor_fa:${DIR}/Plugins/loftee/human_ancestor.fa.gz,conservation_file:/your/path/phylocsf_gerp.sql

Using this argument with this file, the error disappears in my case.

Best,

Jordi
