How to load/import/extract Axon Instrument .abf file 2.0.4 version?

[shuohuang]

Hi all:

I am using Axon 200B patch clamp amplifier to perform electrophysiology data acquisition. I think I am using the latest version of the ClampEX software which is the generating abf data files that I can not read using LabView anymore. 

I used to be able to process abf files following this way when the file format is abf 1.8 or earlier:

I guess Axon modified the file structure so that I can not read it anymore. I am attaching the file in the latest format and 1.8 format. Really hope someone can help me out to get the latest format read out in LabView so that I can perform batch data processing much more easily.

I have the same problem. How can you get the problem solved? Any update?

Hello!

Though not an ideal option, you can export the new data format to the old data format:

If you can find a dll for reading the new format ABF files, you can also look into using that dll in LabVIEW using our Call Library Function Node:

Dear DahlmanR:

Thanks for your reply. I think both your solution will work. 

Solution 1 is not ideal but I guess if we can not find any better solution, it may be the way to go. 

I am more interested in solution 2 and I did find a package of documents from Axon, which contains a dll file. You think it is the one that we can use to solve the problem?

Hi, I just published a couple of VIs for reading ABF 1.8 & ABF2 files. You can have a look there, please tell me if I could improve anything.

Cheers!
