 <sup>&nbsp;&#9733;</sup> For some Mac OS X, it is worth noting that the default [BSD _xargs_](https://www.freebsd.org/cgi/man.cgi?xargs) does not offer all the functionalities required by _fqCleanER_.
 However, the expected [GNU _xargs_](https://www.gnu.org/software/findutils/manual/html_node/find_html/xargs-options.html) (here named `gxargs`) can be easily installed using [_homebrew_](https://brew.sh) (i.e. `brew install findutils`).
 Of note, _fqCleanER_ first looks for the `gxargs` binary on the `$PATH`, and, if missing, for the `xargs` binary.<br>
 <sup>&nbsp;&#x2726;</sup> When compiling the source code of [_Musket_](https://musket.sourceforge.net/homepage.htm#installation), it is recommended to edit its _Makefile_ to increase the value of the macro `MAX_SEQ_LENGTH` (e.g. 1000) in order to avoid any problem during the execution of _fqCleanER_.
