Layers stack methods

View stored layers

To view all stored layers:

print(omi.layers)

omilayers will print a table with the following columns:

• name: User assigned name to the layer.

• tag: User assigned tag to the layer.

• shape: Number of rows and columns of layer in the form NrowsxNcols.

• info: User assigned description to the layer.

Tags are used as a way to group layers. To view layers with a given tag:

print(omi.layers("tag_name"))

omilayers will print a table with the following columns:

• name: User assigned name to the layer.

• tag: User assigned tag to the layer.

• info: User assigned description to the layer.

Rename layer

To rename a layer called foo_layer to bar_layer:

omi.layers.rename(layer='foo_layer', new_name="bar_layer")

Delete layer

To delete a layer with name foo_layer:

omi.layers.drop("foo_layer")

Search for layer

The more layers the user adds, the more difficult it gets to keep track of what kind of data each layer holds. To search for layers that include for instance the term “colA”:

omi.layers.search("colA")

omilayers will search for the term “colA” in the following places:

• The names of the layers.

• The description of the layers.

• The column names of the layers.

After the search is completed, omilayers prints the names of the layers where the term was found.
