hi @jeantristanb, the gtc2vcf plugin can peek into the IDATs and can convert GTCs to VCF. However, you cannot convert IDATs to VCF with the plugin, as the IDATs do not contain genotypes which are generated by the Illumina GenCall algorithm. The main reason gtc2vcf allows you to peak inside the IDATs is to help you guess which array the IDATs were generated with. This might guide in understanding which manifest files to use when converting IDATs to GTCs and when converting GTCs to VCF.
