Hi, are you using the option "retention time correction"? It could be the reason of the problem. With the retention time correction the gap filling module takes one sample randomly and fills all its gaps creating a model of the retention time shifts with the rest of the samples one by one. After that, this sample with the complete set of peaks is used to create the retention time model for all the other samples and fill the gaps. Any idea about how to improve it?

Its been running all day on my 210 samples and only 32% complete. Considering the RANSAC alignment only took 20 mins or so on the same data, this seems surprising. I would have though the RANSAC routine would be more computationally demanding than merely filling in empty rows? Perhaps this may be worth looking at in a future revision?
