I am reproducing Manta run as seen in the logs of illumina basespace RNA-Seq Alignment tool v1.1.1 :

[LOG][2021-03-12 20:58:56.377]03/12/2021,20:58:56.193,Launch process:  \

--referenceFasta='/path_to_genomes/genome.fa' \
--config '/opt/illumina/Isis/2.6.25.18/Workflows/WholeGenomeRnaSeqWorker/scripts/configManta.py.ini'

The file shown in the line above configManta.py.ini is however no were to be found. The Manta user guide states in the linked section

Options listed in the file: ${MANTA_INSTALL_PATH}/bin/configManta.py.ini

The files are however missing. I am using Manta version 1.6.0 from bioconda.

Your insights will be much appreciated!
