 🛠️ Bug fixes:
 
+* Fixed [Issue #137](https://github.com/DataLab-Platform/DataLab/issues/137) - Arithmetic operations and signal interpolation: dialog box with parameters is not displayed
 * Fixed [Issue #136](https://github.com/DataLab-Platform/DataLab/issues/136) - When processing a signal or an image, the analysis result is kept from original object
   * Before this fix, when processing a signal or an image (e.g. when applying a filter, a threshold, etc.), the analysis result was kept from the original object, and was not updated with the new data. Thus the analysis result was not meaningful anymore, and was misleading the user.
   * This is now fixed: the analysis result is now removed when processing a signal or an image. However it is not recalculated automatically, because there is no way to know which analysis result should be recalculated (e.g. if the user has applied a filter, should the FWHM be recalculated?) - besides, the current implementation of the analysis features does not allow to recalculate the analysis results automatically when the data is modified. The user has to recalculate the analysis results manually if needed.
