How to use spades operate a fasta file, especially simulated reads in fasta format from badread? #1305
Comments
Will you please attach the input file? Per error message – it is not a valid FASTQ file |
Please attach the file itself |
ok, thank you so much. |
I cannot reproduce the problem, everything is ok for me. So, likely there is some local problem. In any case, these reads are not valid SPAdes input as Illumina reads cannot be that long. |
OK,thanks for your reply. And I want to know what if I want to assembly a short sequence like virus, how should I use these nanopore reads, thanks. |
Per SPAdes manual (https://ablab.github.io/spades/input.html): To run SPAdes you need at least one library of the following types:
Illumina and IonTorrent libraries should not be assembled together. All other types of input data are compatible. SPAdes should not be used if only PacBio CLR, Oxford Nanopore, Sanger reads or additional contigs are available. |
thanks so much. |
