apply_chain_wise
#
- biotite.structure.apply_chain_wise(array, data, function, axis=None)[source]#
Apply a function to intervals of data, where each interval corresponds to one chain.
The function takes an atom array (stack) and an data array (ndarray) of the same length. The function iterates through the chain IDs of the atom array (stack) and identifies intervals of the same ID. Then the data is partitioned into the same intervals, and each interval (also an
ndarray
) is put as parameter into function. Each return value is stored as element in the resultingndarray
, therefore each element corresponds to one chain.- Parameters:
- arrayAtomArray or AtomArrayStack
The atom array (stack) to determine the chains from.
- datandarray
The data, whose intervals are the parameter for function. Must have same length as array.
- functionfunction
The function must have either the form f(data) or f(data, axis) in case axis is given. Every function call must return a value with the same shape and data type.
- axisint, optional
This value is given to the axis parameter of function.
- Returns:
- processed_datandarray
Chain-wise evaluation of data by function. The size of the first dimension of this array is equal to the amount of chains.
