Hi All, When I model missing loops in a homomultimer using Modeler, I always model just one monomer and then make copies and align them with the original monomers.

On September 14, 2026, I submitted Job L7VGGZ7PMNMYBWAR via the web service of ChimeraX 1.12. The task was a Modeller refinement to fill in the internal missing loops for the 9IM3 dodecamer (12 chains, ~4,800 residues).The job status returned as "failed". The stderr is empty, and the stdout cuts off midway through the bond angle violations list, with no models summary provided. While IL00010001.pdb and B99990001.pdb were generated, DL00010001.pdb is missing. In B99990001.pdb, all 12 chains are present with no missing residues; however, the residue numbering runs continuously from 1 to 6564 rather than being partitioned by individual chains.I suspect the job was forcefully terminated due to the computation time exceeding the server's single-task limit. Could you please clarify the following:Is there a maximum time limit per job for this service?For multi-chain tasks of this scale, do you recommend submitting them chain by chain?Can B99990001.pdb be reliably used as the final structure with the loops completed?I look forward to hearing from you. Thank you very much for your time and assistance.Best regards,On Sep 17, 2026, at 1:25 AM, 张晓飞 via ChimeraX-users <chimerax-users@cgl.ucsf.edu> wrote:您好：我与2026年9月14日使用ChimeraX 1.12软件的web service中提交了Job L7VGGZ7PMNMYBWAR（modeller refine 补 9IM3 十二聚体 12 条链的 internal missing loops，~4800 残基）：status = failed，stderr 为空，stdout 在键角违反列表中途截断、无 models summary，IL00010001.pdb和 B99990001.pdb 存在但 DL00010001.pdb 不存在，其中 B99990001.pdb12条链都在，并无缺失残基，但是残基编号直接从1-6564，并未按链划分。疑似计算时长超过服务器任务上限被强制终止。请问该服务是否有单任务时限？此类多链任务是否建议分链提交？B99990001.pdb 是否可以作为补全残基后的结构使用？十分期待能够收到您的回复，谢谢。
