tClamp18 offers a series of Igor Pro GUIs for data acquision via an InstruTECH ITC-18 AD/DA board. tClamp18 is optimized for whole-cell patch-clamp recordings in voltage- and current-clamp modes but it may be used for general data acquision purposes as well. tClamp18 is quite flexible in channel settings harnessing 8 ADCs and 4 DACs with any kinds of amplifiers of different manufactures (Axon, HEKA, Werner, DAGAN, Nihon Kohden etc.). tClamp18 is also very flexible in stimulus protocol: up to 4 analog waveforms made in Igor Pro and 4 digital outputs can be combined at 5 micro second resolution with an intuitive virtual 4 channel stimulator. Thus, tClamp18 is an ideal solution for simultaneous multi-cellular whole-cell recordings with several patch-clamp amplifiers with untypical complex stimulus protocol. tClamp18 is similar to pClamp software (Axon) and PatchMaster software (HEKA), but superior to them in a sense of flexibility and its cost. tClamp18 does not implement telegraph functions, so experimenters need to be careful not to forget switching gain settings when you change amplifier gain during experiments.

This code has been tested in Igor Pro version 6.3.7.2. for Windows and supposed to work in Igor Pro 6.1 or later. This code is supposed to work for Windows Vista, 7, 8, 10 and Mac X also, but tested only in Windows XP and 7. This code is supposed to work any host interfaces (PCI-18, PCI-18V3, or USB-18), but has been tested only with USB-18.

- Launch your Igor Pro.
- Initialize tClamp18 by clicking "tClampInitialize" in Initialize submenu of tClamp18 menu.
- Select a DAC ADC setting in tClamp18 menu.
- Select a Oscillo Protocol in tClamp18 menu.
- Select a Stimulator Protocol in tClamp menu, if you want to use it.
It is very convenient if the above initialization processes are automated.
- StimTTLPrep.ipf Select "StimTTLPrep" in Macros menu.
- StimTTLPrep.ipf depends on tClamp18_SettingEPC7PLUS_700A.ipf, tClamp18_PairedPulseStimulation.ipf, tClamp18_E7PM7A_TTL_Stim.ipf files, which can be found in expample zips.
