Hello,
I am using BrainVision Analyser to analyse EEG theta-activity in a reality-monitoring exclusion memory paradigm (two encoding conditions; imagine/perceive and three target designations at retrieval; target/non-target/new). I have used the Complex Morelet Wavelet function. I have attached print screens of my pre-processing steps for your reference.
I am struggling to export the values for statistical analysis. From reading the BrainVision manual, I understood this could be done via the Area Export function. I have attached a print screen of the options available in case I have missed something obvious. However this always produces the same error "no history domain with frequency domain found". I can get an export using the Generic Data Export function. This exports power for each participant at each time point for each condition separately. I can do this for each participant (44) and condition (4), but this will be time consuming; I wanted to check this is correct before I commit to it. Alternatively, if I have misunderstood something entirely, I would greatly appreciate your input.
Thank you for taking the time to read this. I look forward to hearing from you,
Amie
While this does not directly answer your question, have you reached out to your local Brain Vision/Products distributor or the support office?
I have found them to be extremely helpful with answering similar questions I have had when navigating the functions of the BVA2 software.
I hope this helps, but I will continue to look for an answer for this specifically, as I'm going to need to export study-level data in a similar manner soon!
Thank you for taking the time to reply - I haven't contacted them before, but I shall take your advice. I will keep you updated if I get a reply.
Dear Amie,
The BrainVision Analyzer 2 has a Solution called "Wavelet Data Export" that was designed to export time-frequency (TF) data.
You double click on the last step of your TF analysis and then open this solution. On the Wavelet Data Export menu you can define the parameters of the data export: the time range (ms); the frequency range (e.g., lower and upper frequency layers); the output values (e.g., real or complex, sum or average).
Also (and importantly), you can create an history template for this export step in order to avoid repeat it manually for every subject. To take full advantage of this , check the option on the Wavelet Data Export that allow you to append the data to the output file each time a new subject is processed.
Hope it helps!
Best,
Margarida
Thank you for getting back to me. I have just realised I don't have the solutions installed that you mentioned! I will try and update this and then hopefully I can export the data.
Here it is!
Put this file in the Solutions folder and it will work.
Best,
Thank you very much for your help - the file you sent works :) Your guidance has been invaluable!!
