In this article, we will show you how to download and play Spades on Linux using SPAdes Genome Assembler, a software tool that can assemble genomes from various types of data. We will explain what SPAdes Genome Assembler is, how to download and install it on Linux, and how to use it to play Spades on Linux.

How to Download SPAdes Genome Assembler on Linux

SPAdes Genome Assembler is a software tool that can assemble genomes from various types of data, such as Illumina, IonTorrent, PacBio, Oxford Nanopore, Sanger, and others. SPAdes Genome Assembler can also handle metagenomic, plasmid, transcriptomic, biosynthetic, viral, and other data sets. SPAdes Genome Assembler has several features, such as:

It can perform de novo assembly, meaning it can assemble genomes without using a reference genome.
It can perform hybrid assembly, meaning it can combine data from different sources and technologies.
It can perform error correction, meaning it can detect and fix errors in the input data.
It can produce graphs, statistics, and reports of the assembly results.

To download SPAdes Genome Assembler on Linux, you have two options:

You can download SPAdes Linux binaries from GitHub by following these steps:
- Go to the directory where you want to install SPAdes and run this command: wget [1](https://github.com/ablab/spades)
- Extract the downloaded file by running this command: tar -xzf SPAdes-3.15.5-Linux.tar.gz
- Go to the bin directory by running this command: cd SPAdes-3.15.5-Linux/bin/
You can download SPAdes Linux binaries from the official website by following these steps:
- Go to [2](https://cab.spbu.ru/software/spades/) and click on Download SPAdes binaries for Linux (64-bit only).
- Save the file in the directory where you want to install SPAdes.
- Extract the downloaded file by running this command: tar -xzf SPAdes-3.15 -5-Linux.tar.gz
- Go to the bin directory by running this command: cd SPAdes-3.15.5-Linux/bin/

After you have downloaded and extracted SPAdes on Linux, you can install it by running this command: ./spades.py --test. This will run a test assembly and check if SPAdes is working properly.

How to Play Spades on Linux using SPAdes Genome Assembler

To play Spades on Linux using SPAdes Genome Assembler, you need to have some input data that you want to assemble. You can use your own data or download some sample data from the SPAdes website or other sources. For example, you can download a sample data set of E. coli genome from [3](https://cab.spbu.ru/files/release3.15.5/ECOLI_SC_LANE1.fastq.gz) and [4](https://cab.spbu.ru/files/release3.15.5/ECOLI_SC_LANE2.fastq.gz).

Once you have your input data, you can launch SPAdes and choose the data type that matches your data. For example, if you have Illumina paired-end reads, you can use the -1 and -2 options to specify the files for the first and second reads. For example, if you want to use the sample data of E. coli genome, you can run this command: ./spades.py -1 ECOLI_SC_LANE1.fastq.gz -2 ECOLI_SC_LANE2.fastq.gz -o spades_output. This will create a directory called spades_output where the assembly results will be stored.

Next, you can set the command line options that control the assembly process. For example, you can use the -k option to specify the k-mer sizes that SPAdes will use for assembly. You can also use the -t option to specify the number of threads that SPAdes will use for parallel processing. For example, if you want to use k-mer sizes of 21, 33, and 55, and 4 threads, you can run this command: ./spades.py -1 ECOLI_SC_LANE1.fastq.gz -2 ECOLI_SC_LANE2.fastq.gz -k 21,33,55 -t 4 -o spades_output. You can find more options and their descriptions in the [SPAdes manual].

Finally, you can run the assembly pipeline by pressing Enter. SPAdes will start assembling your data and display the progress and messages on the screen. Depending on the size and complexity of your data, the assembly may take from a few minutes to several hours or days. When the assembly is finished, SPAdes will print a message saying “SPAdes finished successfully”.

To view and analyze the output files and graphs, you can go to the spades_output directory and open the files with your preferred tools. For example, you can open the spades.log file to see the summary and statistics of the assembly. You can also open the scaffolds.fasta file to see the assembled sequences in FASTA format. You can also open the assembly_graph.fastg file to see the assembly graph in FASTG format. You can use tools like Bandage or Gepard to visualize and explore the assembly graph.
