Everyone loves BLAST. We love BLAST too. What's not to love? BLAST is easy to understand and it still represents the gold standard in local alignment algorithms. But BLAST doesn't like parallel computing. Not even in the latest NCBI release. If your lab produces small data sets, you are probably familiar with the NCBI BLAST service. If you have medium or large data sets, perhaps you have access to a powerful computer and you can afford to wait a few weeks or even months to see whether your alignment is finished or you need to start over. Or perhaps you are among the lucky few who have access to a GPU machine equipped with a GPU BLAST code. Whatever your situation, if you are producing data from Next Generation Sequencing (NGS) experiments, you have likely encountered the limitations of currently available BLAST implementations. '''CrocoBLAST''' is for you.
'''CrocoBLAST''' offers a platform for running and managing your BLAST calculations. With '''CrocoBLAST''', you will always know how much time it will take to run a BLAST job, and you will be able to pause or interrupt a BLAST job at any time and retrieve partial results. Another key aspect of '''CrocoBLAST''' is that it is extremely hugry. As such, it takes the sequences in the input file, and munches them into small pieces that will be fed into the classical BLAST algorithm. This enables you to run very large BLAST jobs efficiently even with minimal computational resources (say, your desktop machine), while ensuring that the output is identical to what you would obtain if you were to run BLAST (minus the headache and the constant frustration while you wait for the job to complete... or not).


Below you can find the '''CrocoBLAST''' user manual, which contains all the information you need in order to make efficient use of '''CrocoBLAST'''. Note that you need not install '''CrocoBLAST''', as it is sufficient to download the files from the webpage and unzip them. You may run '''CrocoBLAST''' from the graphical interface or directly from the command line. Using the graphical interface currently requires Java - but don't worry, you probably have it already. If you get in trouble, see the [[CrocoBLAST:Technical_details | Technical details ]] page.
