At the same time, the settings are applied to the current experiment. When these controls are run (and user is forced to run them if the Irena is loaded and preferences are not found), they save preferences in special folder Igor maintains for users. This has some interesting features, so please, read carefully: These settings are actually saved on a given machine as well as the experiment. This is necessary as more and more control is provided on each platform to user and therefore default fonts and font sizes may not be appropriate any more for the panels I design. These controls enable user to customize font used on control panels therefore this enables customization for a given platform. If you want to overwrite hti sbehavior, hold down any modifier key (alt, cmd/ctrl/shift…). NOTE: Position and size is recorded ONLY when panel size is changed, not when it is just moved. When being recreated, the panel will move and scale back to its size. Keep in mind, that if this checkbox is not selected, every time you scale up/down a panel, its position and size is recorded. NOTE: Panel controls are applied immediately to all existing panels, graph controls are applied ONLY to the newly created graphs (and only those which were upgraded to this behavior).ĭo NOT restore Panel Sizes” controls if panels are restored to the last used size and position when other they are recreated (they were closed and a tool is opened again) or when some existing experiment is reopened. “Configure image default fonts and names” in the SAS menu will create panel with some controls common for all tools, like font type & size and how legend names are handled. Or when you want to send file to someone who may not have Irena installed, remove Irena package so he/she does not get errors on load when Igor tries to load Irena Including “offloading” Irena package from the experiment, so it does not slow down the operations when you want to do something else. Therefore, it may be worthwhile to simply select high enough Qmax for fitting anyway.įrom the Last menu Item you can get “About” panel stating current version and Igor versions, which it has been tested on.ĭownload and open Manual, request manuscript, sign up for mailing list and do few other operations you may find useful. This is done automatically, behind user back – but note, that it can cost cpu and therefore increase time per calculation of the model. This is fixed now for Modeling, Unified Fit, and Size distribution by adding additional Q points (up to 100 new points) to extend the data to 10* slit length and after the model is calculated and slit smeared, the data are truncated back to original user range. This means, that it is not possible to select for modeling data from small-qs to only 0.02 A -1 ONLY. Typical slit length of the USAXS instrument is 0.02-0.03 A -1, so the high- q range needed to be at least 0.08 A -1. However, some Irena tools have limitations when fitting smeared data: due to need to smear data and the way it is handled by Irena routine, the modeled range of data (the high- q selected for modeling and fitting) have to be larger than slit length. It is nearly ALWAYS better to fit slit smeared data than to desmear the data and then fit them. If more than one set of data is in a folder, it is impossible to figure out which data the result belongs to.ĭata manipulations tools, which create a new (e.g., merged) data set will create a new folder.įitting slit smeared data is major Irena advantage. Most Irena operations will pick the data from this folder and if user decides to save the results from any modeling, return proper Irena result back to this folder. It means, that within Igor experiment (to see it graphically, open Data Browser - in Igor menu “Data”, select “Data Browser”) is located folder which name represents your sample name. Irena uses strictly “Folder = sample” philosophy. Not only we have “input” data, but most Irena tools will generate some “output” data - e.g., Size distribution, Unified fit model intensity vs Q, etc. These are “input” data for Irena, typically either generated by Nika or Indra data reduction packages or imported from other data reduction packages using one of the Data Import tools. Optionally we can have other information - intensity uncertainty, q-resolution etc. Typical SAXS or WAXS data will have x-axis (q vector) and y-axis (intensity). Data in Irena need to be stored within Igor experiment as “waves” which is Igor term for “array” of data.
