It seems the tree has no branches and BIOMOD does not manage to get the optimal number of leaves. </div><div>My take on that is that your species is very difficult to model for CTA and it does not manage to find any good combination of variables explaining the distribution. </div><div>Perhaps we need to make an error trap around this call as this is not the first time we got this error, which is not a BIOMOD bug, but rather the failure of CTA to find an optimal number of leaves. </div><div>I will suggest removing the model for this species.</div><div><br></div><div>Looking at the code you sent with this message and the other one, I would also suggest:</div><div><br></div><div>Removing some techniques. Some generally performed quite poorly compared to the other ones. CTA and ANN are the weakest ones. SRE is more like a null model, the most liberal. I would drop the three. </div><div>Same for evaluation, you do not need to use both TSS and KAPPA, they are quite redundant. Just keep TSS, less influenced by prevalence and ROC. </div><div><br></div><div>I would recommend using "random" for pseudo absence instead of SRE or circle which tends to over fit a bit the data.</div><div>I take the liberty to send you this paper in press with Methods in Ecology and Evolution that discuss the different strategies for selecting pseudo-absence:</div><div><a href="http://www.will.chez-alice.fr/pdf/BarbetMEE2012.pdf">PDF</a></div><div><br></div><div>Hope it helps,</div><div><br></div><div>Wilfried</div><div><br></div><div><br></div><div><br></div><br><div><div>Le 7 févr. 2012 à 05:06, jason b mackenzie a écrit :</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><font class="Apple-style-span" face="Arial">Dear all,</font></div><div><font class="Apple-style-span" face="Arial"><br></font></div><div><font class="Apple-style-span" face="Arial">I recently had a BIOMOD run crash mid-stream after 20+ species appear to have run successfully.
