15.12.2. Save Reanalyzed ASCII Sweep Files
WinLTP normally saves reanalyzed files that had been blanked, filtered, or blanked+filtered ADsweeps
that were obtained from WinLTP’s default ASCII files (Fig. 16.1.1).
WinLTP can also save reanalyzed files that blanked, filtered, or blanked+filtered ADsweeps that were
obtained from general ASCII ADsweep files (with our without a header), and saved as general ASCII
ADsweep files.
This is primarily for using WinLTP to remove the stimulus artifact blanks from general ASCII
ADsweeps for later reanalysis with another program, but also to have WinLTP signal average and
digitally filter ASCII ADsweep files (although a lot of other programs signal average and digitally filter).
The file extensions for loading the 'Raw' general ASCII sweep files and converting and saving them to the
Averaged, Blanked, and/or Filtered ASCII sweep files is as follows:
Raw -> Blanked
*.B
Raw -> Filtered
*.F
Raw -> Blanked & Filtered
*.BP
Raw -> aVeraged
*.V
Raw -> aVeraged & Blanked
*.VB
Raw -> aVeraged & Filtered
*.VF
Raw -> aVeraged, Blanked & Filtered
*.VBF
(An Averaged, Blanked & Filtered (*.ABF) file extension was not chosen because of obvious conflict with
Axon Binary Files.)
15.13 Converting WinLTP ASCII ADsweep Files to Axon Binary
Files in Reanalysis Program
Converting WinLTP ASCII ADsweep Files to Axon Binary Files (*.abf) in the Online/Acquisition program
has been described in Section 13.1.
In WinLTP 1.10, the ability convert WinLTP ADsweep files to Molecular Devices Axon Binary File (ABF)
files was added. The Axon Binary File format originated and is used by Molecular Device’s pClamp
programs, and by many analysis programs including Molecular Devices ClampFit, Synaptosoft’s
MiniAnalysis, Axograph Scientific’s AxographX, Bill Heitler’s DataView and Christoph Schmidt-Hieber’s
StimFit32 (which can also directly analyze WinLTP’s ASCII ADsweep files).
Note however, that WinLTP’s ability to convert WinLTP ADsweep files to Axon Binary Files is only
available in WinLTP’s Advanced Version or during the Demotrial Period.
