在提交作業是，運行中出現中斷，有個錯誤為：

Load case 4 has been given in step 0 on a *correlation option  which references a base motion *psd-definition option. However, this load case does not exist on any *base motion option in this step.

Analysis Input File Processor exited with an error.

請問各位大神，這是哪里出錯了？該怎么修改？萬分感謝
