<div dir="ltr"><br><div>Hi Nick -</div><div><br></div><div>Thanks for the reply.</div><div><br></div><div>An update: for the time being I just went back to not using remove_invariant_features and ignoring those warning messages. However, processing one of my subject's data (so far only just one hangs, out of 7 that finish) hangs PyMVPA s.t. it never resolves. My understanding is that these warnings I'm getting:</div><div><br></div><div><span style="font-stretch:normal;font-size:11px;font-family:Consolas">WARNING: Obtained degenerate data with zero norm for training of <LinearCSVMC>. Scaling of C cannot be done.</span><br>
<span style="font-stretch:normal;font-size:11px;font-family:Consolas"> * Please note: warnings are printed only once, but underlying problem might occur many times *</span><br></div><div><br></div><div>and the underlying issue (of some dead voxels being included in the dataset) should not actually crash the system -- presumably searchlights centered at voxels that include these dead voxels might be weird, but not more than that . If that assumption is right, and I can give you something to help determine what's gone awry, let me know.</div><div><br></div><div>S</div></div>
