Project creation

In this example, we create a Project from scratch

import spectrochempy as scp

Create a project with subprojects

proj = scp.Project(
    scp.Project(name="P350", label=r"$\mathrm{M_P}\,(623\,K)$"),
    scp.Project(name="A350", label=r"$\mathrm{M_A}\,(623\,K)$"),
    scp.Project(name="B350", label=r"$\mathrm{M_B}\,(623\,K)$"),
    name="project_1",
    label="main project",
)

proj.projects_names

['P350', 'A350', 'B350']

Add datasets to a subproject

Create two datasets:

ir = scp.NDDataset([1.1, 2.2, 3.3], coords=[[1, 2, 3]])
ir

NDDataset — float64, size: 3

NDDataset_fcf9b45b

tg = scp.NDDataset([1, 3, 4], coords=[[1, 2, 3]])
tg

NDDataset — float64, size: 3

Add them to the A350 subproject:

proj.A350["IR"] = ir
proj.A350["TG"] = tg

Access project members

print(proj.A350)
print(proj)
print(proj.A350.label)
print(proj.A350.TG)

Project A350:
    ⤷ IR (dataset)
    ⤷ TG (dataset)
Project project_1:
    ⤷ P350 (sub-project)
    ⤷ A350 (sub-project)
       ⤷ IR (dataset)
       ⤷ TG (dataset)
    ⤷ B350 (sub-project)
$\mathrm{M_A}\,(623\,K)$
NDDataset: [float64] unitless (size: 3)

Save and reload

proj.save()

PosixPath('/home/runner/work/spectrochempy/spectrochempy/build/~gallery_examples/core/e_project/project_1.pscp')

newproj = scp.Project.load("project_1", allow_unsafe_legacy=True)
newproj
