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. Therefore sampling every 0.2 seconds will miss the positive and negative peaks. 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). Some highlights of Igor Pro 8 improvements include: Long object names, increased from 31 bytes to 256 bytes. Here are graphs, also from the attached experiment, showing the original data (data0 vs timeW - I renamed your waves for simplicity): Igor Pro 8 contains hundreds of improvements, including 20 new operations, 5 new functions, a new NetCDF XOP, and the Igor Filter Design Laboratory (a separate product in Igor 7 and earlier). The output is a waveform with the X data represented in the wave's X scaling. 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 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. Semi-Automated Routines for Functional Image Analysis (SARFIA) IGOR.6.30.x-1. Semi-Automated Routines for Functional Image Analysis (SARFIA) IGOR.7.00.x-1.08 Release File: Updated help files.ġ.02A: Removed unnecessary includes from CustomStart.ipf, added a missing procedure file (Difference.ipf).ġ.02: Fixed a bug in the LoadMovie operation that would not load images with a single frame. Added version information ("About") in the menu. Added a method to analyse overlays (see help file).ġ.03: Added thresholding based on the à trous wavelet transform and extraction of the timecourse of all pixels in a binary or MultiROI ROI mask. Added support for the latest ScanImage versions (3.6). Updated manual and help file with new and missing functions.ġ.04: Many minor updates. Improved automatic parameters for stack registration (added flag /PSTK when calling ImageRegistration). Image stacks with 3 layers will now be displayed as a grayscale stack rather than a RGB image. Repaired functions to measure the relative positions in a structure ("IPLPosition"). Added function DrawCoMPositions to label the relative positions of centers of mass (rather than their number). Added function PopCorrelate to calculate the normalized cross-covariance of traces in a a populationwave. Go to the Downloads page or select the HelpUpdates for Igor Pro menu item within Igor Pro 9 to get the latest release. A list of notable changes for this release is included below. Many minor bugfixes.ġ.05: Added new function DistanceTransform to calculate the distance transform of a binary image. A new release of Igor Pro 9 is now available for all platforms. Fixed a bug when >256 traces were isolated, #256 was identical to #0, #257 to #1, etc. 2D distance transform now uses faster WaveMetrics code (new feature in ImageTransform) ġ.07: Added loader for. Added ROIstats for time series and for 3D time series. Improved center of mass calculations when drawn ROI size is larger than the actual image feature. To install, unzip and copy the contents of User Procedures into the WaveMetrics>User Procedures folder, the contents of Igor Procedures into the WaveMetrics>Igor Procedures folder and the contents of Help Files into the WaveMetrics>Igor Help Files.ġ.09: Multithreaded "RemoveROI" to speed up removal of small (or large) ROIs Minor improvements.ġ.08: Requires Igor Pro 7 or newer. This release contains a detailed help file, describing all functions and a manual describing the control panels.
