How to extract Neurosynth studies with specific features in NiMARE?

Thanks so much for your help! I got some more questions about how I can modify the dataset object in NiMARE:

  1. Neurosynth dataset does not seem to contain the sample size of each study for an accurate ALE analysis. Can I manually add sample size as a column to the dataset?

  2. I am also wondering how neurosynth retrieves the peak coordinates from each paper. Does it simply retrieve all the reported coordinates (in the table for example) regardless of which contrast the study performed (if the study examined more than one type of contrast)? If so, to what extent can I modify the existing peak coordinates, such as removing unwanted contrast in the dataset?

  3. Finally, is it possible to add new studies to the neurosynth dataset locally?

Thanks!
