+====== Troubleshooting ======
+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 [[Sift:Tutorials:Tutorial_Overview|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.
+===== Working Data =====
+=== All Grouped Data ===
+All data/workspaces that were queried, regardless of what is plotted.
+=== All Plotted Groups ===
+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)
+=== All Workspaces ===
+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)
+=== All Highlighted Data ===
+Only data that is highlighted
+===== Graph is missing data =====
+If you plot data and there are empty data points, you may end up with a straight line at -9999999:
+{{:DataMissingGraph.png}}
+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 [[Sift:Application:Plot_Options_Dialog|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.
