All
the procedures have been written on a Macintosh with Wavemetric's IgorPro
3.14, a data analysis software which is especially useful for scientific
applications. The procedures should be able to run on all platforms and IgorPro
3.x versions. I appreciate IgorPro for its ability to produce high-qualitiy
EPS graphs and its powerful programming possibilities with its macro-derived
language.
Most of the procedures contain a more or less extensive header or download
detailled information (
,
768 kB, 20 pages, German)
. Almost all use some conventions like x-waves end with "X",
y-waves with "Y", waves don't use wave scaling etc. The (text) procedure
files are only a few kilobytes. Most of the procedures will contain some code
that the normal user won't need.
| Importing data | |
| ReadASCIIfile.ipf |
reads a variety of ASCII data formats as produced by Spekol 1100, Uvikon 942, PE LS-50B or other spectrometer formats with logging their origin, labelling waves according to the orginal file name. All the settings can be controlled by a context-sensitive panel. |
| ReadJCAMPfile.ipf | reads JCAMP files from Bruker Vector 33, Spekol 1100 and PE Lamda 9 as scaled waves |
| ReadAutolabfiles.ipf | reads impedance spectra, voltammogramms and other formats from Autolab data files |
| ReadCV.ipf | reads cyclic voltammogramms as exported by BAS systems. It reads and displays header informations and can color subsequent segments differently |
| Read_TN6500_Spectra.ipf | reads Tracor Northern 6500 ASCII exported spectra |
| General tools | |
| AusreisserEntfernen.ipf | sets outliers as NaNs or kills them |
| TagForCursorA.ipf | sets a tag at cursor A which contains x-, y- values, values from a wave or other combinations as you choose. It can find a maxima/minima between two cursors and label it automatically. |
| MakeLegend.ipf | creates a legend with a given number of entries based on the waves displayed in the top graph. Waves can be associated by their trace index or by a number index in their wavename. |
| ColorWaves.ipf | colors all displayed waves from a start to an end color based on their trace index |
| CopyGraphOrTable.ipf | makes copies of all or a set of waves in a graph or table under a different name (prefix added) |
| Integralberechnung.ipf | calculates area below x-y wave pair curve considering different cursor positions |
| KurveAlsGauss.ipf | fits three Gauss waves to a x-y wave pair (constraints possible), parameters are logged in a table |
| ScanString.ipf | emulates scanf command from C |
| Working with timedrive data | |
| TDzusammenhaengen.ipf | assembles several timedrives into one wave |
| Kurvenparameter.ipf | calculates average, noise and drift for a signal |
| BestAnsprechfu.ipf | determines 90 or 95% response time based on a slow or a fast response model |
| Events2Tags.ipf and ExtEvents2Tags.ipf | attaches tags with content of a text wave along a displayed wave and a more general version |
| ExtractValuesFromWaves.ipf | extracts values of all curently displayed waves in a graph at a one or two given cursor location and logs them in a table |
| ExtractYYValuesFromWaves.ipf | extracts averaged y-informations from two waves as well as the x-information, displays it in a graph and logs it in a table |
| ZoomInTimedriveForData.ipf | automates finding interesting parts along a displayed wave for value extraction |
| Optical spectroscopy | |
| AbsSpectraUtilities.ipf | designed to work with specially designed Igor Text files containing a large number of absorbance spectra |
| BestExtinktionskoeff.ipf | calculates the fraction of each species in a two species absorbance series |
| MakeSternVolmerPlot.ipf | creates a Stern-Volmer Plot from a I0/I vs. concentration plot and can fit a one/two-component Stern-Volmer fit to it and log the coefficients into a table |
| MakeSternVolmerFit.ipf | fits various models (one-site, two-site, continouous distribution) to a model |
| Spektren2Wellenzahlen.ipf | converts spectra from nm into cm-1 domain with necessary spectra bandwith intensity correction |
| generates a 3D spectra plot from a row of spectra or from more general data | |
| Impedance spectroscopy | |
| ImpedanceUtilities.ipf | can fit/ simulate various equvalent circuits to a large series of impedance spectra data following a flexible enumeration convention. Works also on individual spectra. Co-authored with others, see doc. |
