Open Microscopy Environment

Using the API I know I can retrieve the image name from the image object, i.e.

Code: Select all

In [11]: iid = 1
In [12]: img = conn.getObject( 'Image', iid )
In [13]: img.getId()
Out[13]: 1L
In [14]: img.getName()
Out[14]: 'cell10_ome.tif'

Now, when I try to retrieve the image name from the list of children from a dataset

Code: Select all

list_of_images = []
# connect as above
for project in conn.listProjects():
    for dataset in project.listChildren():
        links = dataset.getChildLinks()
        for image in links:
            temp = {}
            temp['iid'] = long(image.getId())
            temp['name'] = image.getName()
            list_of_images.append( temp )

print json.dumps( list_of_images )


produces the output

Code: Select all

Since the names should the filenames at import, am I using the methods incorrectly? Is this an error? I don't have the same issue trying to retrieve the names of datasets or projects.

Hi,

You simply need to use dataset.listChildren() in exactly the same way you do for project.listChildren().
This will give you a generator of ImageWrappers (same as you get with conn.getObject("Image", iid).

Will.
