====== Installation of tRNAscan-SE 1.23 ======

===== Additional libraries ===== 

No additional library is necessary.

===== Procedure =====

Here is the procedure for installing tRNAscan-SE from its source code:

  * The archive is downloaded from the web in ''/home/bioubuntu'', decompressed and the newly created folder is moved into ''/opt/bio/sources''.

  * This folder should belong to ''root'' and its permissions set to ''755''.

<code bash>
% sudo chown -R root:root /opt/bio/sources/tRNAscan-SE-1.23
% sudo chmod 755 /opt/bio/sources/tRNAscan-SE-1.23
</code>

  * Once you are in ''/opt/bio/sources/tRNAscan-SE-1.23'', you need to do small edits in the ''Makefile'' before compiling:
<code bash>
BINDIR=/usr/local/bin
LIBDIR=/usr/lib/tRNAscan-SE
MANDIR=/usr/share/man
</code>

  * After that, compilation is a snap:
<code bash>
% cd src
% sudo make && sudo make install
</code>
