<div class="">Dear rcicr-users,</div>
<div class=""><br class="">
</div>
<div class="">A new version of rcicr (0.3.4.1) is available on CRAN now. It fixes some minor bugs and more importantly: it adds several features, like a new noise type (Gabor), a setting to change the number of spatial scales of the noise, and a new default
scaling method, called independent scaling. It should be completely backwards compatible, so your old scripts will work as they should when you update the package.</div>
<div class=""><br class="">
</div>
<div class="">Here's the full list of changes since version 0.3.0:</div>
<div class=""> </div>
<div class=""><b class="">NEW FEATURES:</b></div>
<div class="">* Added independent scaling. Works like matched scaling but maintains the zero point. Is the new recommended default for generating a single base image.</div>
<div class="">* Added Gabor noise option. Generate stimuli with generateStimuli2IFC(..., noise_type='gabor'). Almost all functions have been affected in refactoring. </div>
<div class="">* Added option to specify number of spatial scales</div>
<div class="">* Added computeCumulativeCICorrelation. Computes cumulative trial CIs correlations with final/target CI. Use for instance for plotting </div>
<div class="">* Added label parameter to batchGenerateCI, which adds custom identifiable labels to jpegs</div>
<div class="">* Added targetpath parameter to CI generation functions, so CIs will not by default be placed in working directory, but in ./cis subdirectory</div>
<div class="">* Added batchGenerateCI to deal with data from any reverse correlation task that does not use inverse noise. This function can be used for a 1IFC, 2IFC with independently generated stimuli, 3IFC, etc. </div>

<div class=""><b class="">CHANGES:</b></div>
<div class="">* Changed output of autoscale: scaling factor is no longer part of the list of classification images that is returned</div>
<div class="">* Changed progressbar to dplyr progress bar, no longer dependent on tcltk (so no more dependency on xquartz on OS X). Also adds time estimation.</div>
<div class="">* Suppressed warning messages if directory for stimulus or ci output already exists.</div>
<div class=""><br class="">
</div>
<div class=""><b class="">FIXES:</b></div>
<div class="">* Bugfix: images not saved as jpegs when scaling is set to anything other than autoscale in batchGenerateCI and batchGenerateCI2IFC</div>
<div class="">* Bugfix: When using pre 0.3.0 Rdata file, the parameter matrix will now be truncated to the appropriate numbers of parameters</div>
<div class="">* Bugfix: NA's in by parameter of batchGenerateCI2IFC() get ignored instead of making R crash. Thank you Elze Ufkes for reporting this bug!</div>
<div class="">* Bugfix: target path error message for generateCI2IFC()</div>
<div class="">* Fixed targetci bug (should be empty list by default instead of boolean) in computeCumulativeCICorrelation</div>
<div class="">curves of trial-final/target CI correlations to estimate how many trials are necessary in your task</div>
<div class="">* Bugfix in generateCINoise: added possibility of just one stimulus/response</div>
<div class=""><br class="">
</div>
<div class=""><b class="">REFACTORING:</b></div>
<div class="">* Renamed generateCI2IFC to generateCI and moved it to rcicr.R as it is a general function, and not just for 2IFC reverse correlation tasks</div>
<div class="">* Created generateCI2IFC wrapper function (wraps generateCI) for backwards compatibility</div>
<div class="">* Renamed old generateCI to generateCINoise to differentiate between generateCI and generateCINoise</div>
