W: Extract ion centroids (single/multi-dataset)
Brief description
Extract ion images. These images can be used in visualisation, unsupervised or supervised training.
Parameters
Tag (identifier) (type - string)
Tag to use for the object.
m/zs (type - array)
M/z values.
Filename (type - string)
Path to peaklist file.
Filename (reference) (type - string)
Path to peaklist file.
PPM tolerance (type - number)
Integration window around each m/z during image extracting. This is an approximate value and
might be slightly smaller or larger, depending on how the mass bins are aligned.

Attributes
| Attribute | Value | Description |
|---|---|---|
| Multiple allowed | True | Allow multiple instances of this task in a workflow. |
| Task can fail | False | 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 | False | Task requires ion mobility data. |
| Task can fail (with ion mobility) | False | 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). |
