Macros

Features of Macros A group of recorded Lab. Chart commands, which can be executed with a single command All recorded commands are played back in the exact sequence they were recorded Help to speed up repetitive and tedious tasks Automate recording and analysis of data © 2006 ADInstruments Pty Ltd

Macro Types of Macros n n n Sampling (or Recording) Analysis Combined Sampling &

Applications of Macros Example Uses of Macros n Sampling l Change the settings for stimulation (Output 1, 2 or Isolated Stimulator) l Set up triggering l Save data as a new file l Provide a message or alert l Add comments © 2006 ADInstruments Pty Ltd

Applications of Macros Example Uses of Macros n Analysis l Repeatedly log waveform parameters into the Data Pad l Print selected data (e. g. from the Zoom window) l Find comments and select data before, after or around the comment © 2006 ADInstruments Pty Ltd

Hints for Writing Macros n n n Write down all the steps involved (keep a copy in Lab. Chart’s Notebook) Break complex operations into several macros then combine them into one macro Modify the steps of an existing macro to suit your needs Use Lab.

Formula (Estimation) Data Block Size = No. of Channels x Sampling Rate x Recording Duration x 2 Recording Duration = Data Block Size No. of Channels x Sampling Rate x 2 Example The maximum continuous recording duration for 3 channels, sampled at 1 k/s is: Recording Duration © 2006 ADInstruments Pty Ltd = 1 GB/(3 x 1000/s x 2) = 166667 seconds = 46 hours

Formula (Estimation) Example The maximum continuous recording duration for 3 channels, sampled at 1 k/s is: Recording Duration = 1 GB/(3 x 1000/s x 2) = 46 hours Therefore if the Data Block was saved, you could then record another new Data Block of similar duration. File Recording Duration (2 Data Blocks) © 2006 ADInstruments Pty Ltd = 46 x 2 = 92 hours
