I am not sure whether I can ask this question here or not. I have a set of paired end fastq files and I want to compare with the my data with the HMP project. My data is de-multiplexed. But I could not find any information whether data which in HMP website are de-multiplexed. Where do I know the same and where I can find the barcode information for those data?
And My second part of question : I have two sets of fastq files with different read length. For example one set of files has 251 bp and the second set has 276 bp. How do I analysis together? I encountered an error while giving the truncated length in DADA2 step. How can I achieve this?
