The tool commented above, PDDF, was added per user request (utilizing two different methods to obtain PDDF). The intention in use was allow easy testing on what happens when one changes data range, parameter range, some other parameters. It also very much depends on users and user feedback to decide which solutions are correct and are incorrect. So it may not be the best for analysis of extensive data sets. Large data sets number crunching was not considered early on and is pain to graft onto existing design, even though it has been done for two tools at this time. The attempt was from beginning to provide graphical feedback to user how these parameters influence the model (where possible) to facilitate better scientific understanding.Īs bad side effect, it is challenging to script many tools, so lot of analysis needs to be done "manually". It is bit overwhelming as number of controls, needed to make it scientifically correct and flexible, is relatively high. However, one needs to understand the philosophy of this package - from early stages it is "GUI driven" package with as many controls as "appropriate". Irena was originally intended for materials science but as users proposed new tools, it has grown well beyond the original scope.

There are even users, who reuse Irena code in their own programming and that makes them more productive.

That is great, as there actually are Irena users, who read the source code and propose improvements, changes, and provide independent verification of the code.

javascript:emoticon(':!:')įurther major advantage of Igor Pro is, that the software is distributed as ASCII source code compiled before use on user computers, and therefore all of the Igor packages are by default open source. And e-mail reply by support on Sunday at 11pm is common. Really, I requested new function for my needs and I had beta version on my computer 24 hours later, and updated Igor version was out in few weeks. And Wavemetrics user support is second to none.
But the features of Igor Pro are very much worth the price, which is compared to other similar platforms very reasonable. Igor Pro is commercial package and current direction in SAS software is clearly towards non-commercial platforms. I do not want to dwell too much on the other packages so I do not misrepresent them, but as author of Irena I think I can provide some background to help potential users. As far as I can say none of them is specifically bio-package, but each contains at least some tools which can be useful to bio community. There is really not much competition among these packages, as each is targeted slightly differently. For few years the authors of these packages are trying to improve interoperability among these packages - with limited success. There are three major sources of SAS software for Igor Pro in the US - NIST, APS (Irena/Nika/Indra, this audience needs to consider only Irena), and ORNL (Ken Littrell). Probably they are related to this publication by S.R. I could not find these utilities online (may be I didn't look well enough). Littrell about utilities for SANS data reduction and graphical analysis - also for IGOR Pro but apparently not related to Irena. So my experience with Irena was not exactly positive but may be it is good for other goals.Īt the SAS09 conference in Oxford there was a presentation of K.C. Using the Irena PDDF tool I did not manage to obtain the P(r) function for good quality BSA data.

Instead of a manual there are video files in QuickTime format which explain step-by-step how to achieve this or that The Irena GUI can be quite confusing, it takes a while just to load a file, then a while just to plot it IGOR Pro exists for Windows and Mac only (not for Linux), I used the Windows version IGOR Pro is commercial software (they have a trial version).My goal was to analyze SAXS data from biological objects, particularly to obtain P(r) functions automatically.
I actually tried the Irena package (v2.32a) for IGOR Pro about half a year ago.
