Log Viewer tab

Obtain the log files from a print

The following buttons are available:

• Fetch & merge : Move and merge the log files available from the <BaseExportDirectory> to the database in their respective substrate folders. Merges the 5 different log files of each object and generates the .mat report files. Once merged, an object file is displayed in the Print field list and is also accessible by the VCG tab (substrate plots, collision detection,…). Merging is also a necessary step for the Iontip Calibration procedure.

• Plot Substrate : Display an overview of the selected substrate in the bottom left figure based on the .mat report files available.

• Save Space : Save disk space by deleting original log files. The merged .mat report files remain available in which all log data is stored.

Log file selection

The log files available in the Print field list can be selected. When a printed object is selected, a Printed Object figure opens with each voxel (color-coded) that is contained in the file. Additionally, selected printing statistics are displayed in the top right of the tab.

Printed object figure

The color code is the following:

• regular voxel : voxel completion was detected after approaching to the voxel’s position
• missing voxel : the voxel was not printed, the printing stopped before reaching this voxel
• collision voxel : the voxel completion detection triggered while moving to the XY voxel position
• redundant voxel : voxel completion detection triggered while approaching the voxel Z level, but after reaching its XY position

Available interaction with the figure:

• rotate (left click dragging in the figure)
• zoom (wheel)
• pan along one axis (left click on the selected axis and drag)
• restore default view (house icon)
• datatips (left click on a voxel with the datatip icon toggled)

Print data

The Print data section summarizes the key values related to the selected object.

Pressure range

The Pressure range indicates 1 value when pressure is the same for all voxels, and the [min max] range when different values were defined in the printfile.

Substrate list context menu

The contextual menu options for the Substrate list are:

• Notes : Open the Notes dialog or create a note files for the selected substrate. This can be used to write or read additional information about this substrate.

• Open in Explorer : Open the substrate folder in Windows explorer.

Print field list context menu

The Print field list context menu options are :

• Analyze deflection data : Display different curves showing the recorded data during printing.

• Send to Iontip Calibrator : Load the print log data in the Iontip Calibrator tab. A valid calibration curve is only obtained when loading a suitable calibration file.

• Send to Print File Generator : Send the print file coordinates to the Print File Generator tab. The print file is accessible in the list with scripts under LogViewer.

• Delete .log and .mat files : Delete all log and report files related to the selected object. Deletes the object and all its information from disk.

• Delete .mat file only : Only the merged .mat report file of the selected object is deleted. The .mat files is recreated by clicking the Merge button.

• Delete .log file only : Only the log files are deleted. All the information on the object is still accessible in the .mat report file. This is a useful function to save disk space.

Plot Substrate

The bottom left shows the selected substrate overview created with Plot Substrate. All merged .mat files available are used to plot the objects viewed from the top. Objects plotted in green were fully printed, object in red miss at least one voxel. Row and column labels are added to identify each object on the substrate. Transformations added in CAPA are also included in the preview via the PL log file.

Holding the left click and dragging draws a zooming box around the area of interest. Plot Substrate can be used to reset the view.

Show image

The Log Viewer tab can display images that are taken of each printed object (in SEM or optical microscope for example). To use this feature observe the following instructions with case-sensitivity.

1. Select the relevant substrate and use Open in Explorer.
2. Create a folder called image and copy the images of the object in this folder.
3. Images must be named SubstrateName_r[Row Number]c[ColumnNumber][_suffix] to fit their imaged object name. The suffix can be anything to differentiate multiple images of the same object. Row and column numbers must be in a two-digits format (01-99).

Example

If the substrate name is Sub1 and the row is 1 and the column is 5, the image name is Sub1_r01c05, placed in a folder ./analysis/Sub1/image.
If there are multiple images taken of the same print field, add an underscore and a suffix. The extension of the image should not be changed. Any image supported by the MATLAB function imshow will be shown in the GUI. Folder and file names are case sensitive.

The LogViewer only displays images if the checkbox Show image is checked, a print field is actively selected in the print field list and that object has images properly named (two-digits format, case sensitive, etc.). If multiple images are associated with the same print field, the first image will be displayed and a > icon will appear to go to next image and move through all images.
