Excel automatically arranges the tabular data in a spreadsheet.

The *Format as table* feature under the *Styles* pane works well for sorting data. Save the file in the XLSX format to make persistent changes.

## Rows

There is one row for each program (*Measure*, *Empty*, *Clean*, etc.) started on your BactoBox®. This reflects what you see in the:

* [History screen](https://help.sbtinstruments.com/encyclopedia/user-interface/menu-system#history) in the [Dash](https://help.sbtinstruments.com/encyclopedia/software/user-interface) user interface
* Measurements page in the [Access](https://help.sbtinstruments.com/encyclopedia/software/access) user interface

We sort the rows by the *Start time* column. The newest row comes first.

## Columns

The columns include (non-exhaustive list):

<table><thead><tr><th width="306">Column name</th><th>Description</th></tr></thead><tbody><tr><td>Program</td><td>Program name. E.g., <em>Measure</em>, <em>Empty</em>, <em>Clean</em>, etc.</td></tr><tr><td>Start time (YYYY-MM-DD hh:mm)</td><td>Format: YYYY-MM-DD hh:mm<br><strong>Uses the time zone of your BactoBox®.</strong></td></tr><tr><td>Measurement ID</td><td>Mnemonic measurement ID. E.g., A03 or F98.<br><strong>Rolls over at Z99 to A00.</strong><br>Blank for some utility programs.</td></tr><tr><td>Device ID</td><td>The unique ID of your BactoBox® device. E.g., <em>bb2241039</em>.</td></tr><tr><td>Software version</td><td>Version of the BactoBox® software used <em>when the program started</em>. E.g., <em>2026.01</em>.</td></tr><tr><td>Flow cell ID</td><td>Unique ID for the flow used for the measurement. E.g., <em>2D8B16T</em>.</td></tr><tr><td>Cells/mL</td><td>Measured cells/mL concentration.<br><strong>May show, e.g., "&#x3C;30000" including the </strong><em><strong>less-than</strong></em><strong> sign.</strong><br>Blank for some utility programs.</td></tr><tr><td>Total/mL</td><td>Measured total/mL concentration.<br><strong>May show, e.g., "&#x3C;30000" including the </strong><em><strong>less-than</strong></em><strong> sign.</strong><br>Blank for some utility programs.</td></tr><tr><td>Total/mL - Cells/mL</td><td>Measured other/mL concentration.<br><strong>May show, e.g., "&#x3C;30000" including the </strong><em><strong>less-than</strong></em><strong> sign.</strong><br>Blank for some utility programs.</td></tr><tr><td>Conductivity [uS/cm]</td><td>The electrical conductivity in µS/cm of the measured sample liquid.<br>Blank for some utility programs.</td></tr><tr><td>Errors</td><td><a href="../error-codes">Error code</a> and explanation. E.g., "1200: The conductivity is lower than 1600 uS/cm".<br>Blank if there are no errors.</td></tr><tr><td>ECC factor</td><td>Empirical concentration correction (ECC) factor. BactoBox® adjusts the intact cell concentration based on the ECC.<br>Part of gating settings defined the CRS file.<br>Blank for some utility programs.</td></tr><tr><td>Classification filename</td><td>File name of the CRS file that defines the gating settings. E.g., <code>BacTotal_v2024-02.crs.json</code>.<br>Blank for some utility programs.</td></tr><tr><td>Classification limits</td><td>Phase and amplitude “gates” that BactoBox® uses to  classify the objects in your sample vial.<br>Part of gating settings defined the CRS file.<br>Blank for some utility programs.</td></tr></tbody></table>

## Short-form and long-form

The *summary.csv* file exists in two forms:

<table><thead><tr><th width="100">Form</th><th width="100">Row limit</th><th>Notes</th></tr></thead><tbody><tr><td>Short</td><td>200</td><td>Found in the <em>USB drive</em> that appears when you connect your BactoBox® to your computer.</td></tr><tr><td>Long</td><td>∞</td><td><a href="../access/pages/download-summary">Download via Access</a>.</td></tr></tbody></table>
