TDMS

Upload NI TDMS files from the Python client or NI FlexLogger®. The Python client converts each TDMS channel to a channel named <group>.<channel>, with spaces replaced by underscores. It takes timestamps from each channel’s wf_start_time and wf_increment properties, or from a time channel you name.

Upload a file

Python

Install the Python client’s tdms extra:

pip install "nominal[tdms]"

Then upload the file to a new dataset:

from nominal.core import NominalClient
from nominal.tdms import upload_tdms

client = NominalClient.from_profile("default")
dataset = upload_tdms(client, "test_run.tdms", name="Test run 12")

To add a file to an existing dataset, use upload_tdms_to_dataset.

NI FlexLogger®

Add the Nominal-TDMS-Upload plugin to your FlexLogger® project, as in Load the plugin in FlexLogger®. It uploads each TDMS file once FlexLogger® closes it.
