 +====== Getting specific fasta sequences from reference file ====== 
 + 
 +In case you need to retrieve a specific sequence from a larger fasta file, use one of my perl scripts. Simply provide a pattern that it needs to match in the definition field and it will retrieve the sequence. The **-f** is the reference file, **-o** is the output file name, and **-query** is the pattern it will try to match. 
 + 
 +<code> 
 +perl /home/mkatari/PerlScripts/getFastaName.pl -f ../blast/Mesculenta_147_v4 \ 
 +    -o scaffold12498.fa \ 
 +    -query scaffold12498 
 +</code> 
 + 
 +====== Creating the blast database ====== 
 + 
 +Before we can actually perform the blast, we need to prepare the database using **makeblastdb**.  
 + 
 +<code> 
 +makeblastdb -in cassavaV5 -input_type "fasta" -dbtype "nucl" 
 +</code>
