P: Average ion mobility heatmap (single-dataset)

Brief description

Generate average ion mobility heatmap based on fraction of the pixels (this task will also automatically generate an average mass spectrum).

Parameters

Filename (type - string)

Filename to use for the object. This can be very helpful when you want to e.g. compare or export spectra

Proportion (type - number)

Proportion of pixels to use for the task.

Normalization tag (type - string)

Tag to use for normalization.

Help

Rather than applying a normalization to the entire dataset, we apply it as needed to each task at hand.
You can compare the effect normalization has on specific task by repeating it with different normalization.
In some cases, its advised to use 'multi-dataset' normalization, in particular when doing comparisons.

Normalization name (type - string)

Name of the normalization.

More Information

This task will extract average ion mobility heatmap for each dataset in the dataset folder.

The average heatmap will be based on the specified proportion (of pixels/frames) of the dataset.

  • If the value is equal to 1.0, then all pixels will be used for this task.
  • If this value is less than 1.0, e.g. 0.5 then 50% of all pixels will be used. The 50% is selected evenly throughout the dataset.

We don't apply normalization on the entire dataset which means that we can (and should) apply normalizations on certain tasks, such as generating heatmaps. You can select normalization tag (source) and normalization name (e.g. TIC).

Attributes

Attribute Value Description
Multiple allowed True Allow multiple instances of this task in a workflow.
Task can fail True Task is optional and can fail without causing the entire workflow to fail.
Step can fail True Sub-tasks of this task can fail without causing the entire task (and workflow) to fail.
Requires ion mobility True Task requires ion mobility data.
Task can fail (with ion mobility) True This task uses ion mobility data but it is allowed to fail, without causing the entire workflow to fail.
Allowed in reference dataset True Task is to be performed on a 'reference' dataset. This will allow for multiple analyses to be performed on the same dataset, without cluttering or duplicating certain tasks (unused at the moment).
