Listed below are the solutions to common problems that have been reported to the Has-Motion support team. For step-by-step instructions on how to use the various features available in Sift visit our Tutorials Page. If you have a problem that has not been covered below or in the Sift tutorials feel free to e-mail the support team at support@has-motion.ca.

All data/workspaces that were queried, regardless of what is plotted.

Only perform work on the groups that are plotted on all plots. Work can be performed on:

• All workspaces for those groups (regardless on if they are plotted or not)
• Plotted Workspaces (works on entire workspace, even if only one trace/C3D is plotted)

Only perform work on the groups that are plotted in the active plot.

• All workspaces for those groups (regardless on if they are plotted or not)
• Plotted Workspaces (only works on the plotted data, so if only one trace/C3D is plotted, that is what will be used)

Only data that is highlighted

If you plot data and there are empty data points, you may end up with a straight line at -9999999:

Most calculations (mean, standard deviation, etc) will handle empty data points without an issue, so you can choose not to plot data not found:

• In the Options Dialogue
• Uncheck “Show data not found”
• Click “Refresh Plot”

You can also choose to exclude this data by selecting this data, right clicking → Exclude → Exclude trace (raw data).

NOTE: Most calculations handle data not found, however, the input to PCA should not contain any missing data points.
