AstroIO.jl

I/O interface for astrophysical simulation codes

Installation

]add AstroIO

or

using Pkg; Pkg.add("AstroIO")

or

using Pkg; Pkg.add("https://github.com/JuliaAstroSim/AstroIO.jl")

To test the Package:

]test AstroIO

Documentation

• Dev — documentation of the in-development version.

For beginners, it is highly recommended to read the documentation of PhysicalParticles.jl.

Usage

using AstroIO

Gadget2

Suffixes gadget2, Gadget2, GADGET2 are supported

header, data = read_gadget2("snapshot.gadget2", uAstro)

write_gadget2("output.Gadget2", header, data)

# If only data provided, a default header would be generated
write_gadget2("output.GADGET2", data)

Supported units: uAstro, uGadget2, uSI, uCSG.

Use FileIO interfaces

header, data = load("snapshot.gadget2")
save("FileIO.gadget2", header, data)

Output CSV

write_csv("output", csv) # No suffix

Save and load with JLD2

write_gadget2_jld("output.jld2", header, data, uGadget2)
write_jld("NoHeader.jld2", data)

header, data = read_gadget2_jld("output.jld2")
data = read("NoHeader.jld2")

# Or simply use JLD2 interfaces
@load "NoHeader.jld2"
