-      Using shell wildcards to merge multiple FASTQ file pairs in a single command

-     You can use shell wildcards (* and ?) to give a pattern that matches the FASTQ files you want to merge. For example, this will merge all R1 files in the current directory:

It is completely self-contained: it does not require configuration files, environment variables, third-party libraries or other external dependencies. There is no setup script or installer because they're not needed. To install it, all you do is download or copy the binary to a directory that is accessible from the computer where you want to run the code. For convenience, you may want to <a href="binary_filename.html">rename the binary file to usearch</a> to avoid typing long names like <span class="ManText">usearch6.0.98_i86linux32.</span></p>
