ROI Buffer

The ROI buffer dialog box is displayed when you select Save ROI to buffer on the ROI Statistics dialog box and when selecting ROI -> View -> ROI Buffer from the Measure menu

The dialog is also displayed when selecting ROI -> ROI Buffer -> ROI->buffer from the Measure menu.

Number of decimals: Specifies the number of decimal places included when ROI-values are copied to clipboard of file.

Copy: 

Copies all ROI s for the current slice to the clipboard (i.e. the ROI s visible in the list).

Save all: 

Saves all ROI s in the Buffer to a text file (.txt). This text file can be loaded directly into Excel as a semi colon delimited ASCII file. Note that nordicICE always uses ‘.’ as the decimal delimiter. If your PC is set up with ‘ ,’ as the decimal delimiter (see Regional Options in Settings in Windows) you need to replace all ‘.’ with ‘,’ in the saved text file. You may also have to tell Excel to import the columns as individual numbers (Data->Text to Columns option in Excel).

Save buffer: 

Saves the ROI buffer as a binary file (.buf) which can be re-loaded into nordicICE. Can also be activated from the popup menu of the active window or from the main menu. See “ Saving and Loading ROI Specifications ”.

Delete ROI: 

Delete the selected ROI in the ROI Buffer list.

Update ROI: 

When a ROI in the list is selected, this ROI will appear in the image and can be modified. After modification, pressing Update ROI will store the changed ROI back to the Buffer.

Delete Buffer: 

Deletes all the entries in the ROI Buffer.
