What is a tree in root?
A TTree, often called in jargon tree, consists of a list of independent columns or branches, represented by the TBranch class. Behind each branch, buffers are allocated automatically by ROOT.
How do you use TChain?
Once a chain is defined, one can use the normal TTree functions to Draw,Scan,etc. Use TChain::SetBranchStatus to activate one or more branches for all the trees in the chain. Definition at line 33 of file TChain. h….

What is the main root of a tree called?
taproot
The first root to grow of the primary roots is called the taproot, and it emerges as a radicle from a germinated seed. The taproot continues to grow as the tree matures. Not all trees grow deep taproots, especially if adequate nutrients are to be found close to the surface.
What do roots do?
root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
How do root help a plant?
The roots of a plant take up water and nutrients from the soil. They also anchor the plant to the ground and keep it steady. The stem carries water and nutrients to different parts of the plant. It also provides support and keeps the plant standing upright.
What do roots do for plants answer?
What is buildbuildindexonerror?
BuildIndexOnError : If any of the underlying TTree objects do not have a TTreeIndex, all TTreeIndex are ‘ignored’ and the missing piece are rebuilt. Definition at line 3505 of file TTree.cxx. Copy a tree with selection. The returned copied tree stays connected with the original tree until the original tree is deleted.
How to create a branch of a class in root?
Create a new branch with the object of class classname at address addobj. Starting with Root version 3.01, the Branch function uses the new style branches ( TBranchElement ). To get the old behaviour, you can: Note that with the new style, classname does not need to derive from TObject.
How are index files produced?
No value is produced but index files are written to the current working directory. This function generates a hash table (an index) for a reference genome, in which keys are subreads (16mers) and values are their chromosomal locations in the reference genome. By default, subreads will be extracted in every three bases from a reference genome.
What is the built index used for in SQL?
The built index can then be used by Subread ( align) and subjunc aligners to map reads (Liao et al. 2013). Highly repetitive subreads (or uninformative subreads) are excluded from the hash table so as to reduce mapping ambiguity.
