Export data
Save recorded channels to a folder you can open in Excel, a notebook, DIAdem or LabVIEW. One sheet does it, from wherever you are looking at data.
Open the sheet
| From | Control |
|---|---|
| Replay | Download at the top right |
| A run in Replay's runs tab | Download… in its menu |
| Live, after a run stops | Download on the Run saved note (when files are not saved automatically) |
| A camera tile in Replay | Download this camera as shown |
The sheet, Download data, opens filled in from the screen: the window or run you were on, and the channels you were showing. In the console, a run's page has its own Download data.
Four steps
| Step | Question | Choices |
|---|---|---|
| When | Which stretch of time? | a run, or a time range: last 5 min, last 15 min, last hour, a run…, exact times… |
| What | What goes in it? | On screen, Everything or Choose |
| How | How should it come out? | the format, below |
| Review | You'll get one folder | the folder's files, before anything is written |
Click any step, or any line of the review, to change it. Press Download to write the folder; Show in folder opens it.
While choosing channels, each row shows a coverage bar: on the cloud and this device, on this device only, on the cloud only, or nothing recorded. Gaps show as lost or not running. What the bars mean shows the key.
Pick a format by where it goes next
| Save as | Writes | Open in |
|---|---|---|
| Spreadsheet | CSV | Excel |
| Notebook | Parquet, one file, a row per sample | pandas, DuckDB |
| DIAdem / LabVIEW | TDMS, one file | DIAdem, LabVIEW, FlexLogger |
Details opens the settings. For Spreadsheet, Table picks the shape:
| Table | File |
|---|---|
| a file per rate | time down the side, a column per channel, one file per sample rate |
| one wide file | every channel in one file; an empty cell means that channel did not sample then |
| a row per sample | one file of time, channel, value |
Rate thins the data to a lower rate (default Every sample). CSV sets the column separator, the decimal separator and the number of decimals.
Cameras
| Cameras | Writes |
|---|---|
| As you see it | MP4 with the readings drawn on, frame by frame |
| Clean footage | MP4 without the readings |
If this device cannot write video, the sheet says which cameras it will skip.
What's in the folder
| Item | Holds |
|---|---|
README.txt | what the folder holds, in plain words |
channels.csv | each channel: its file, column, unit and rate |
data/ | the data files |
details/ | files for tools and audit: coverage, gaps and the run's events |
Every data CSV opens with t_us (exact time, microseconds) and t_s (seconds
from the start of the window). A CSV stops at 1,048,575 rows, one Excel sheet,
and continues in _part2.csv, _part3.csv and so on. Each part repeats the
header. The sheet warns you before it splits.
MCAP is not in the sheet. Use the command line:
phloem export '/rig/**' --run <run id> --dest ~/exports --signals mcap.
