![]() ![]() The script runs in MATLAB and exports the time stamps in an excel file. The time stamp extractor requires the full xy diffraction file provided at the beginning of the data set. This is very useful when recording of another time-dependent variable and calibration between the two is necessary for example, when measuring temperature, current, and/or voltage. The time stamp extractor was written to extract the exact time at which each spectra was collected. ![]() Therefor it is an unreasonable assumption that if you have 200 spectra collected at 30 seconds each that the total experiment time is 30×200. Additionally, there is an additional time for computer processing and motor movement before the next spectra is collected. However, the actual collection time is less than each time interval. When setting up an experiment, the operator choses a time interval and total number for spectra collected. Where the first row is the miller index of the reflection, the second row represents the unit of the data, each subsequent row is a collection of peak centers for a given spectra n.įor time-resolved studies it is important to know the exact times at which each spectra was collected. Calculations can beĬomputed in a high throughput fashion by preparing a file of the following format: Least squares method employing the Levenberg-Marquardt algorithm. Rhombohedral, monoclinic, triclinic, and hexagonal structures. It isĪble to compute the lattice parameters and angles for cubic, tetragonal, orthorhombic, The lattice parameter calculator was developed in MATLAB using the fsolve function. Script was written in the Lua language and can be run in the fityk GUI and in the fityk command The most up-to-date software is recommended.įor large data sets it is possible to automate the peak fitting process. There is an older free version and an up-to-date version which one must pay for. The fityk software can be downloaded at http:/.
