![]() How to proceed depends on what you intend to do with the data. I think this problem will affect any kind of straightforward sampling.īecause of the nature of your data, I can't think of a practical way to achieve the goal. Consequently the interpolated data is not a very good representation of your input data.Īlthough this does achieve your goal to "interpolate them all into full strict 5Hz data", the result is likely not what you are looking for. ![]() Igor Pro 8 Highlights Igor Pro 8 Changed and New Features Igor Pro 7 Changed and New Features Igor 6.3 reasons to upgrade Igor 6.3 new features Igor 6.3 changes since release Igor 6.2 new features Igor 6.2 changes since. Therefore sampling every 0.2 seconds will miss the positive and negative peaks. Igor Pro 9 Changed and New Features How to update Previous versions. You can see that the output data, which is sampled every 0.2 seconds, clearly differs from the input data (note the bottom around 12:00 PM). Here are graphs, also from the attached experiment, showing the original data (data0 vs timeW - I renamed your waves for simplicity): Video-Tutorial & Guided Tour IGOR Pro Bildergalerie. If you have problems with this step, see the documentation in uninstallAll3x4x5圆xIgorKeys.txt. ![]() Put them someplace where you wont accidentally overwrite them, such as burned onto a CD-R. The output is a waveform with the X data represented in the wave's X scaling. Backup your own Igor Pro files, and any WaveMetrics-supplied files that you have modified. It uses linear interpolation (/T=1) with "X From Dest" (/I=3). "X From Dest" allows precise control over the X locations at which the input data is sampled. This command is from a function that I wrote called Create5HzData. I did that with this command: Interpolate2 / T= 1 / I= 3 /N= (numOutputPoints ) / Y= $dataOutName timeIn, dataIn All electrophysiological data were analyzed off-line using Igor Pro 6.2 (Wavemetrics) and tabulated in Microsoft Excel. The AR SPM software was not written completely from scratch but builds upon a program called Igor Pro, written by Wavemetrics. I now want to interpolate them all into full strict 5Hz data So your times are roughly 5Hz on average but not consistently close to 5Hz. ![]() I then executed this to find the average time difference: Print mean (timeDiffs ), WaveMin (timeDiffs ), WaveMax (timeDiffs ) Notice that the time differences (last column) are of unequal magnitude.
