Command: DataFileSaveSel

Saves selected channels and their properties from the DIAdem Data Portal to a data file. DIAdem saves the groups and channels in the target file in the same structure as in the Data Portal.

Input Parameters

DataFilename	Specifies the name of a data file with the filename extension and the path. String variable Note  If you do not specify a path, DIAdem uses the NAVIGATOR user path for loading or saving.
FileExportFilter	Specifies the storage method you use to save data from the DIAdem Data Portal to a file. If you do not specify a storage method, DIAdem saves the data with the TDM DataPlugin. String variable The valid values for this variable vary according to the registered DataPlugin. The following values are valid: Value of the variable Meaning Filename extension TDM DIAdem TDM files TDM DD8x DIAdem DAT files DAT TDMS DIAdem TDM streaming files TDMS LVM LabVIEW LVM files LVM ATF ASAM transport format ATF CSV Comma-separated values CSV Note  To specify the value of the FileExportFilter variable for DataPlugins, enable the Recording mode and select a file type in the Save As dialog box. In the script recorded in the script editor, you then receive the value of the variable as a parameter of the DataFileSave command. Note  If you do not save data in the TDM format, group information or properties, for example, may be left out because some formats cannot save all information. Note  If you save data in the CSV format, DIAdem saves only the first channel group. To save other channel groups, you must save the channel groups selectively. Note  If you save data in the CSV format, DIAdem uses a tabulator as the separator.
SelectedChannels	Specifies the data channels that DIAdem saves in the target file. If you do not specify any channels, DIAdem saves all channels. Channel list variable A channel list is a Channel or Channel list object, or a text that refers to one or several channels. For more information about the value range, refer to Channel lists.
[ChnXYRelation]	Specifies that there are x-channel references in xy-channels and that the x-channel is used when copying and moving xy-channels. Boolean Access: Read/Write

Note  If you save data in TDM format, you use the FileSaveDataType variable to specify whether DIAdem specifies the data format automatically, or saves the data format as a floating point value with 64 bits. By default, DIAdem specifies the data format automatically.

Note  The page Loading Bulk Data - General contains important information on the extended loading behavior of TDM and TDMS files.

Examples

The following example saves the channels whose names start with the text Channel from the first group in the Data Portal and all channels from the second group in the file MyExample1.tdm.

Dim oMyChannelList
Set oMyChannelList = Data.GetChannels("[1]/Channel*")
Call oMyChannelList.Add(Data.Root.ChannelGroups(2))
Call DataFileSaveSel(DataWritePath & "MyExample1.tdm", "TDM", oMyChannelList)

oMyChannelList = dd.Data.GetChannels("[1]/Channel*") 
oMyChannelList.Add(dd.Data.Root.ChannelGroups(2)) 
dd.DataFileSaveSel(dd.DataWritePath + "MyExample1.tdm", "TDM", oMyChannelList)
