You can’t even begin to understand biology, you can’t understand life, unless you understand what it’s all there for, how it arose – and that means evolution. – Richard Dawkins
Biology is not merely a mixture of macromolecular chemicals – DNA, RNA, or protein but the dynamic force for life and existence. Therefore the analysis and research of these chemicals to the core is important.
Today we will discuss about a powerful Bioinformatical tool. In this QIAGEN CLC Main Workbench review article, I bring you the ups and downs of the program. This write-up shall cover all the major areas of the CLC Main Workbench like features, pricing, pros, cons, limitations, etc.
Hope this review helps you in identifying your ideal Bioinformatical research tool!
What Is CLC Main Workbench?
CLC Main Workbench is a platform that is used by thousands of scientific researchers across the world for DNA, RNA, and protein sequence data analysis. It allows several data manipulations and executions of algorithms.
The intuitive user interface makes it a comfortable work environment for the user. No advanced computational skills are required to use CLC Main Workbench.
CLC Main Workbench is a complete and all-rounder package for thorough analysis. The various tools and features of CLC Main Workbench are mentioned below:
 Sequence Editing and Viewing
This feature offers to view the sequence. On double-clicking the sequence in the navigation area, the sequence of amino acid or DNA or RNA will appear on the view panel.
- You can zoom in, zoom out, and edit the sequence. There are several choices in Sequence Layout.
- Spacing- no spacing, every 10 residues, every 3 residues frame 1, every 3 residues frame 2, every 3 residues frame 3.
- Wrap sequences- no wrap, automatic wrap, fixed wrap
- Double-stranded- applies only to the double-stranded DNA sequence
- The position of sequences- shows the position of residue in a protein/DNA sequence.
- Sequence label- adding details such as name, accession, common name, etc. to the sequence.
- Annotation type and layouts, restriction sites, motifs, the coloring of residues
- DNA and Protein basic information
- Find function to search within a sequence
- Editing texts, sequences
- Studying and analyzing circular DNA
 3D Molecule Viewer
This feature is excellent. It allows the importing of molecule structure files from the Protein Data Bank (PDB) or its file in the system.
- You can view the protein structure in 3D. The visualization can be customized with different colors and styles of representation. The visualization settings include- hydrogens, fog, clipping plane, 3D projection, coloring, etc.
- You can BLAST search the structure file against the PDB database.
- There are some tools present in the 3D viewer that helps in linking the sequence and the structure. They link the sequence alignments to the molecule structure. The transfer of annotation between the sequence and structure is feasible too.
- The Protein structures can be aligned too.
- The “Generate Biomolecule” option lets you generate biomolecules structures in CLC Main Workbench. A file with information on 3D Coordinates only can be used to generate entire structures. Given below is a biomolecule structure generated from PDB 2R9R.
 Sequence Alignment
CLC Main Workbench is efficient in aligning the nucleotides and proteins by using the Progressive alignment algorithms. This alignment algorithm has three parameters for calculating the gap costs.
- CLC Main Workbench utilizes two algorithms for finding the alignments. One of them is fast and less accurate, while the other is slow and very accurate.
- Alignments can be viewed via Alignment info and Nucleotide info options.
- Just like any other sequence alignment tool, it displays the aligned regions and gaps. The extra choice of editing the alignments is provided here. You can add gaps, delete gaps, copy annotations to other sequences, etc.
- The realignment option lets you create alignment again. It is a powerful tool for editing alignments. It lets you remove changes, adjust the gaps, and edit the fixpoints.
- Join the alignments after you have edited them.
- You can even perform the pairwise comparisons, create comparison tables too.
- Multiple sequences can be aligned too to identify the mutations caused over time. A great way to realize the evolutionary change that might have occurred.
 Evolutionary Relationships
This is a key aspect in understanding the ancient genetic relations between different groups of organisms. The phylogenetic tree construction makes the understanding of such relations easier.
- CLC Main Workbench phylogenetic tree editor allows you to have- circular and radial layouts, data import in CSV format, a tabular representation of metadata, collapsing nodes based on bootstrap values, re-arranging the nodes, visualization of metadata, coloring, and labeling of trees, curved edges, editable nodes, and line size, etc.
- You can construct the tree by these two methods- UPGMA and Neighbourhood Joining method. After construction, you can check the reliability of the result by Bootstrapping.
- Another method of tree construction is the Maximum Likelihood phylogenetic tree.
- You can always adjust the tree layout settings. It can be saved for every tree construction you perform in the future.
- A minimap is an interesting tool that helps in viewing the tree in a very small area.
 General Bioinformatical Analysis
This list of tools lets you analyze the sequences and molecules in a broadway. You can extract the sequences, shuffle them, align them, and view them.
- You can construct the dot plots. They are a powerful visual representation for comparing two sequences.
- You can also calculate the local complexity for both DNA and protein sequences. It is a measure of the diversity in amino acid composition in a protein sequence. Uses the K2 algorithm.
- The general sequence statistics can also be calculated. CLC Main Workbench allows you to find the relevant numbers and figures for any two sequences or more. There are two methods- individual statistics layout and comparative statistics layout.
- For protein sequences, molecular weight, isoelectric points, and aliphatic index can be calculated. You can also estimate the half-life and extinction coefficient.
- CLC Main Workbench allows you to join several sequences together after editing. This leads to the development of “supergenes” that helps in phylogenetic inferences.
 Nucleotide Manipulations/ Analysis
The DNA can be converted to RNA and vice versa. You can reverse complement the sequences. The translation of DNA or RNA to proteins can be done virtually.
CLC Main Workbench allows us to find the open reading frames in a sequence.
 Protein Analysis
CLC Main Workbench lets you analyze a stretch of amino acid anyway you want to. You can estimate the protein charge, antigenicity, hydrophobicity through graphs.
- You can download it from the Pfam database. You can also perform a Pfam domain search.
- You can visualize the 3D protein structure from the database. Perform the model structure search to create models and predict models.
- The secondary structure of a protein can be predicted
- Protein reports can be obtained
- Reverse translation – protein to DNA conversion
- Proteolytic cleavage can be detected
 Cloning and Restriction Sites Identification
Restriction sites can be identified and analyzed. Restriction sites can be created and analyzed. The entire restriction enzyme list can be created.
- CLC Main Workbench lets you create molecular clones and allows editing too. You can insert the restriction sites at the preferred locations. It is manual cloning, hence user experience is quite commendable here.
- Gateway cloning is another added advantage of this feature. You can create entry clones and expression clones.
- A virtual Gel Electrophoresis can be performed and analyzed.
 RNA Structure Prediction
CLC Main Workbench lets you predict the secondary structure of RNA. You can view and edit the secondary structure of RNA. Graphical view and tabular view are feasible. The energy distributions can be studied.
- You can evaluate the structure hypothesis. You can select the sequences for evaluation.
- Construct the structure scanning plot.
