Hello,
I am still new in these matters, I was told to map illumina reads to the human genome. I was given the fastq files and proceeded to use BWA, everything ran smoothly 'til today when I realised the reads I had mapped had the Illimina base qualities instead of Sanger's . This raised several questions: Why can BWA map fastq files with the Illumina instead of Sanger? What are the consequences of this?? Unmapped reads?? miscalled variants?? I am pretty concerned since the mapping took around two weeks and I am not sure if I need to start from scratch again and remap the fastqs in sanger format. Please, any help will be highly appreciated!!
Tanks,
Maria
