Assumption is, that SAS data are in the first 6 columns in the ASCII file. “column 1 – 6” and Qvec Int err” This is checkbox area, in which user needs to select which column of data contains which SAS data. Kill notebook after use, it is not needed for anything else… “Preview” Opens the first selected file in Igor notebook for preview. See below the controls for reduction of data points.

This warning comes when too many points are found.

Actually, they are bad, as they force code to fit too many noisy points. Red text indicating too many data points - lot of data from SAXS instruments contains very high number of data points which are really useless for SAXS data analysis. Sets checkboxes for Column 1 to 6, how many columns were found in the file, etc. “Test” Test import of first selected file. Therefore this “skip lines” should not be usually necessary. Note, Igor will automatically read file structure and skip usually any text header, which needs to be skipped. “Skip lines” if there are known number of lines, which need to be skipped. “ Data extension” if extension is put in this filed (e.g., “dat”) only files with the “dat” extension will be shown in the List of available files. “Match name” enables to use string to select subset of files. Double click on file runs “Test” and “Preview” commands on that file. Use shift - click to select multiple files (on Windows) or cmd – click on Macs (to pick one file at time), shift-click to pick range of files. One or more files here can be selected for import. “ List of available files” lists all files in the current folder on the computer, unless masked by Data extension. Cannot be edited in this window, use button Select data path. “ Data path” this shows the path selected above. “ Select data path” browse to the folder on the computer drive where the data to be imported reside. To make best use of these macros, please use folder structure with folder names being the sample name. Irena macros WILL NOT overwrite old results, but it may be impossible to image out, which data the particular result belongs to…. Note, that when Irena macros save results within Igor experiment, they ASSUME, that they can write simply solution into folder where the SAS data came from. This allows placing multiple data sets in one Igor folder, which I strongly discourage. Use “qrs” naming convention, where the wave with q vector starts with q_andTheDataName, intensity wave is named r_andTheDataName, and error wave s_andTheDataName.

Unless you have USAXS data, do not use USAXS option, this IS NOT correct choice for users from other instruments. When loading data for use with Irena macros, the user needs to decide ahead on naming system, which will be used.

I have included ASCII set of data from our USAXS experiment as example on which user can play and test capabilities, they can be found where the Irena macros are installed, typically Documents/Wavemetrics/Igor Pro 7 folder/User Procedures/Irena/Example Data/.

Users of Indra 2 or Nika produced data can skip this chapter. Irena has various importers - for ASCII, HDF5 canSAS Nexus, & canSAS XML.

This chapter describes how to import various types of 1D SAS and WAXS data in Irena.
