    This is a great tutorial! Agreed with folks there, one of the best tutorials to do sequence alignment I have found. Terrific job!

    This tutorial is awesome but we use botwie to map pair-end reads to a reference sequence of 500bp? If yes how to make an index.

    Thank you for the tutorial. I feel I have a better understanding of this program, now.
    How does one align multiple (as in, say, ~96) reads to a reference with a single command? I tried the "-U" option (my reads are unpaired) and listed all 96 of my samples separated by commas, but the command appears to only align the first sample. The rest it claims, "can't be found," or something to that effect.

    awesome video! Thanks for all the information! Do you perform this analysis with trimmed reads or not trimmed? When I did this with my trimmed file (from cutadapt), I kept getting this message Warning: skipping mate #2 of read '....' because length (1)

  • @pdevine999

    Question for you and you might think its a useless question because I am fairly new to all of this and i am getting massively different results from megahit to spades for example for contig lengths , if I wanted to reverse engineer my contig files or look at the source data and find out exactly where the reads are that these sequences came from , what tool would you use ? I could search manually but the .fq file is 10.5gb , so its pretty much unusable . Both have same min/max overlap settings , so i just want to manually verify . MTIA

    Hi :) Thanks for the tutorial - do you know how to output unaligned reads from the paired reads after the alignment process? Been trying to use the --un-conc command, but can't seem to get it to work

    Are you familiar with QuasR? I am looking to do the same thing in QuasR. Align my reads. I cannot figure out the Anaconda software for Windows. I have not utilized it much and I am under a time crunch. I am attempting to do an alternative to bowtie -f...etc commands. I have already created my index.

      Could be 2 problems
      You don't need bowtie2-align, just bowtie2
      Or you dont have Bowtie2 installed properly > make sure you install with conda to install without any problems

      Nope, M1 Macs are should be still great for bioinformatics! MacOS architecture is the main thing, and that hasn't changed with M1 Macs :)
