BSL PRO 4 Manual - Biopac

216 BSL PRO ManualBatchBatch files (*bcq) is the format used for a saved Batch acquisition setup. All previousconfigurations are saved in this file, so a Batch experiment can be rerun without havingto repeat the setup. When a saved Batch file is opened, the batch setup window appearswith previous graph templates intact. From here, the setup can modified and savedunder the same or a different name. See page 208 for details on setting up BatchAcqusitions.Igor Pro Igor Pro Experiments (compatible with Igor Pro 3.1, 4.0, and 5.0).The waves contained in an Igor Pro packed experiment can be opened (imported) inBSL PRO provided that the packed experiment files comply with the following:WAVEDFLessonsFiles• ≤ 59 waves• no text waves• no complex waves• all waves in Version 2 or Version 5 format (Igor defaults)• all waves one-dimensional (vectors)• all waves multiples of the same fundamental inter sample intervalIf the wave has an associated wave note, it will be used as the channel label.WAV files containing 60 channels or less can be imported. When this format is chosen,the list of available files will be filtered such that only files ending in the “.wav”extension or having the “WAVE” type are shown. When a WAV file is selected, it willbe analyzed to determine if it is compatible with the BSL PRO application.If the file is compatible, a new graph window will be created displaying the datacontents of the WAV file. Each channel will be numbered “Channel n” where n is an increasing digit.These channels will be unitless in amplitude. All of the data will be converted into the 64 bit floating point format for storagein memory and in the ACQ formatted files on disk. The horizontal axis of this graph will be set to time and the sampling rate set tomatch the rate as specified in the WAV file headers. This graph will be marked as an imported graph into which data cannot beacquired. This will dim the start button and any appropriate hardware menu entries thatwould be used to access the invalid hardware settings.Opens files with .eeg and .edf extensions saved in European Data Format (EDF). Data isimported entirely into memory in a newly created graph window titled after thefilename, similar to other file import routines. All scaling factors will be applied to thedata as it is imported, and it will be converted to double precision floating point format.Since EDF format includes data that is not used by BSL PRO, only the following itemsare imported: channel data channel labels units sampling rate (taken from maximum sample rate of all channels)All other information stored in the EDF file will be discarded when the file is imported.Only 60 channels of data can be imported from an EDF file. Channels will be importedstarting with the graph file index 1. If there is a 60th channel, it will be placed into thechannel with index 0. If an EDF file contains more than 60 channels, only the first 60channels will be imported and a prompt will advise that not all of the channels could beimported.Lessons Files is the file format created when running BSL Lessons. These are similar inappearance to BSL PRO *.acq graphs and can be opened in the PRO application whenthis format is selected.Visit the online support center at www.biopac.com
