Manually Enter Data
In 21CFR11 environments, this feature is applicable to members of the Developer group only. |
This process allows the manual entry of pressure data from a sample file with a Complete status. There are two methods for manually entering data into a sample file:
- Copy and paste onto the graph area of the interactive window
- Import data into the interactive window
Copy and Paste Manually Entered Data
- Open a sample file with a Complete status. The file will open to the interactive reports window.
- Right click in the graph area of the interactive reports window, then select Copy data.
- Open another sample file using Advanced option presentation.
- On the Sample Description tab, select Manually entered in the Type of Data group box.
- Click the Advanced down arrow at the bottom of the window, then select Isotherm.
- Ensure that all parameter fields are set appropriately, then click Paste.
Import Manually Entered Data
When importing isotherm data from an external ASCII text file using the Import button on the interactive window, the ASCII text file must use the following rules:
ASCII text file format rules
Data must be in two columns and separated by a comma or white-space. Acceptable column headings are:
- Relative Pressure
- Absolute Pressure (mmHg)
- Absolute Pressure (kPa)
- Absolute Pressure (mBar)
- Quantity Adsorbed (mmol/g)
- Quantity Adsorbed (cm³/g STP)
- Quantity Adsorbed (cm3/g STP)

To import the ASCII text file
- Open a new sample file in Advanced option presentation.
- On the Sample Description tab, select Manually entered.
- Click the Advanced down arrow at the bottom of the window, then select Isotherm.
- Ensure that all parameter fields are set appropriately, then click Import.
- Open the .TXT file. The data from the original sample file is imported and displayed. If an error message appears instead, verify that the .TXT file format is correct.
