I have several idat and gtc files. I want to convert them to standard vcf format to obtain the genotype information. I found that llumnia has developed a python source for parsing gtc files (https://github.com/Illumina/GTCtoVCF). However it requires manifest file / Bead pool manifest.
So my question is :
1) How can I create a manifest file using idat or gtc files that I have ?
2) What is the format of the manifest file, what information does it contain ?
