snap.read.2: Read in a Gadget format 2 snapshot file

In asgr/snapshot: Gadget N-body cosmological simulation code snapshot format 1 and 2 I/O utilities

Description

This function opens the file and reads the header (also checks that the blocks are well written). Then goes trought the full file, checking the blocks. If the block label matches it returns that block.

Usage

snap.read.2(file, what, ndim, type, debug, gas, thin=1)

Arguments

file	File name of the snapshot file to be read.
what	Name of the block to be read.
ndim	OPTIONAL: Dimensions of the block.
type	OPTIONAL: Type of data.
debug	OPTIONAL: add extra information. If debug = 1, then it shows all the blocks present in the file.
gas	OPTIONAL: read only gas files.
thin	How much should the particle data be thinned? thin=1 means all data is read in, thin=10 means every 10th particle is read in. Larger numbers will create more sub-sampled data, and will hugely increase the read-in speed and reduce the memory required. This is useful for making images where only a small fraction of Gadget particles are required.

Details

Opens the file, and read header (also checks that the blocks are well written). Then goes through the full file, checking the blocks. If the block label matches what then it returns that block DATA.

Value

Returns the DATA block from the file.
