Arrow Need Sequence Format Converter

Hi All,

Could anyone recommend the Online Sequence Format Converter?

For example, I would like to convert sequence TXT file to FASTA file, or FASTA to FASTQ. After conversion, I need download it and then upload to some where else.

I really appreciate any response !!

All you need to make a FASTA is to make a > on the first line.

You cannot got from FASTA to FASTQ.

Thumbs up

Thanks a lot for your reply!

After adding > on the first line in the TXT file, How can u save it to FASTA file (with .fasta extension)?

In addition, if there are Thousands of reads/sequences in my TXT file, so I need manually add Thousands of the <, respectively? Not easy

One link here:

It is just a text file so save it as .fa or .fasta

If you need a fasta per sequence you will have to write a script, or use some sort of replace function. If you just want the whole file a fasta you just need to add the > at the beginning.

Sure, since a FASTQ file is still just a text file containing sequence and quality data, you can parse out the sequence only data. But, you cannot take a simple FASTA file of sequences and make it a FASTQ file.
