+ | ===== Wizzard procedure===== | ||
+ | |||
+ | Use the “Group mean data” wizzard. You can find it in the **Tools** main-menu. | ||
+ | |||
+ | In the wizzards first panel you have to select your input data. If the paths to your input data are defined in a “session set file”, you have to check the corresponding box. In the other case, it is assumed that your input data is saved in the “output” folder of your main project in “.d3d”-files. | ||
+ | |||
+ | {{ : | ||
+ | ===== Two-step procedure (deprecated) ===== | ||
+ | This procedure is not recommended but it explains, what is done internally in the automated process configuration based procedure. | ||
+ | - Step: | ||
+ | You have to select some input .d3d files each representing the data of a single session of a subject. It has the following hierarchically structure: | ||
+ | |||
+ | < | ||
+ | < | ||
+ | < | ||
+ | < | ||
+ | ... | ||
+ | < | ||
+ | </ | ||
+ | |||
+ | The phase numberst starts with " | ||
+ | |||
+ | -Step: | ||
+ | The normal data file can then be created from selected input files via the context sensitive " | ||
+ | |||
+ | The hierarchically structure of the output is the same as for the input files. The default behavoir is that parts of the hierarchy (of the input files) of the form | ||
+ | |||
+ | < | ||
+ | < | ||
+ | </ | ||
+ | |||
+ | are averaged inclusive determination of the standard deviation. This results in the output of the form: | ||
+ | |||
+ | < | ||
+ | < | ||
+ | </ | ||
+ | |||
+ | If optional data is available this is simple copied to the output. | ||
+ | |||
+ | The normal data determination can be configured in the process configuration file as following example shows: | ||
+ | |||

+ | ^ phases | LStrides RStrides | blanc seperated list of phase type names | No | ||
+ | ^ frames | 101 | Number of frames all of the phases are resampled to. | No | ||
+ | ^ basedOnSessionMeans | true | If set to false, all single trials are averaged. If not set or set to true the sessions means are averaged. | No | ||
+ | ^ sessionSet | File, which includes a set of volunteers measurement sessions (inter subject) saved in the session set file format. ^ Yes | ||
+ | ^ groups | all defined groups | A blanc seperated list of calc group names. For each normal data are determined. | No | ||
+ | ^ intraSubjectSessionSet | If CMC value should be calculated an additional set of sessions with measurement repetitions of the same subject is needed. | No | ||
+ | |||
+ | If such a definition is available the normal data file can be determined by a single activation of the action " | ||
+ | |||
+ | ====Reference Gait data==== | ||
+ | |||
+ | For gait data the normal data is determined for both sides together with the consequence that the events and phases must be renamed in a side independend manner before averaged. | ||
+ | |||
+ | Mapping of the events: | ||
+ | |||
+ | ^ Original names ^ Description ^ Side independend name | | ||
+ | ^ RHS|LHS at the beginning and at the end of the stride right or left foot strike No name, since these events are deleted | ||
+ | RHS|LHS inside the stride right or left opposite foot strike event OHS | ||
+ | RTO/LTO first occurance right or left opposite foot off event OTO | ||
+ | RTO|LTO second occurance right or left opposite foot off event TO | ||
+ | RG|LG right or left general event for indication of force data (one or 3 events are set) and additional subphases G | ||
+ | |||
+ | Mapping of the phases: | ||
+ | Original names Description Side independend name | ||
+ | RForefootOnly|LForefootOnly ForefootOnly or | ||
+ | OForefootOnly for the opposite foot. | ||
+ | RForefoot|LForefoot Forefoot or OForefoot for the opposite foot. | ||
+ | LPostFootFlat|RPostFootFlat PostFootFlat or OPostFootFlat for the opposite foot. | ||
+ | RInitialDoubleSupport|LInitialDoubleSupport InitialDoubleSupport or OInitialDoubleSupport for the opposite foot. | ||
+ | RSwing|LSwing Swing or OSwing for the opposite foot. | ||
+ | DoubleSupport (no change) | ||
+ | SingleSupport SingleSupport or OSingleSupport for the opposite foot | ||
+ | LSingleSupport|RSingleSupport OSingleSupport for the opposite foot. | ||
+ | LFootFlatOnly|RFootFlatOnly FootFlatOnly or OFootFlatOnly for the opposite foot. | ||
+ | LTerminalDoubleSupport|RTerminalDoubleSupport TerminalDoubleSupport or OTerminalDoubleSupport for the opposite foot. | ||
+ | LStride|RStride Stride | ||
+ | LFootFlat|RFootFlat FootFlat or OFootFlat for the opposite foot. | ||
+ | |||
+ | ====Graphical user interface (GUI)==== | ||
+ | |||
+ | The GUI presents the normal data as gray bands based on the data of the corresponding group (same group name). This default behavoir can be overwritten by setting a normal data group name explicitly in the < | ||
+ | |||
+ | Typically the normal data variables have the same names than the trials data variables. But if this it not the case, in the sheet definition explicit variables names can overwrite the default. See the < | ||
