Following the above question, is the threshold for significant peak different from the amplitude shown in leda2.analysis.amp ?

Hi Mathias, I am interested in getting number of SCRs during the period, and plan to use "length(leda2.analysis.amp)" to obtain it. I noticed that some of the values in "leda2.analysis.amp" is lower than 0.02 muS, which is my desired amplitude threshold. Should i filter these values out, or quoting your 2010 paper " A significant peak is detected if a local maximum has a difference of δ ≥ 0.2 μS from its preceding or following local minimum" - is this already accounted for in the CDA analysis?

Thanks a lot Mathias, I used the Amplitude sum per minute (to account for varying length of data).

Dear Mathais, I have done a batch analysis (CDA) without any events. I wanted to get the SCR amplitude or a measure of overall phasic activity during the entire duration. I have attached the screenshot of variables that pop up after the analysis. Does analysis->phasicData or analysis->amp help me with this in any way? if not, what do these variables stand for?

HI Mathais, Sorry i have managed to process it, it was an error in my part. I forgot to add '\' at the end of the folder pathname i specified, which resulted in the funtion not reading the files properly. Kind regards, Vishnu

Hi Mathais, I tried adding events manually and saving them (which worked), and then tried to do batch analysis using the 'open','leda' arguments. But it keeps saying unable to open file!

Hi Mathias, I was wondering if i could divide the larger eda file into smaller samples of the eda data (~15 seconds each, which corresponds to the event and the window post the event i want to consider), and then do a batch analysis and get the SCR list, since i dont have any events preloaded in my EDA file. Would this method of doing CDA on smaller eda sample (each data file would be about 15 second each) affect its sensitivity/accuracy in anyway?

Ah fair, I will have a look into it. I am assuming this was already done for the GUI interface, when analysing data individually? If you could let me know which script does that, i could compare the two and possibly update the batchanalysis script. Thanks
