several FASTA file to one

Question

[nora]

hi I downloaded several FASTA files (> 200) of RNA 16S to do global alignment, so there is an assembly method of all sequences in a single file without use copy paste thank you

[GenoMax]

so there is an assembly method of all the sequences in a single file

If you just mean combine the contents of many files into one then you can do cat file*.fa > total.fa on linux.

[Ram]

Circular thing on the *.fa glob.

[nora]

yes, but I need to do this on windows

[Joe]

If you use PowerShell, the same command applies.

[GenoMax]

With a regular command prompt on Windows

type file*.fa > total.fa

will do the trick. But use PowerShell if you are using Win10.

Also, you should mention this in your question, as the norm with bioinformatics is a Linux-based OS.

You're just looking to concatenate the files. Isolate all these files are in a dir called fasta_files, and then you can use cat *.fasta >all.fa
