cadence QRC提参遇到hierarchical edge file的error

在后端区发的帖沉了，转这里请教高手
小弟正在尝试calibre LVS+QRC的提参流程，工艺是SMIC 28nm PS，遇到以下两方面问题，求给建议
软件及环境：
1）Redhead 5
2）Cadence IC 6.1

3）Cadence Extraction QRC - Parasitic Extractor - Version 10.1.3-p065

（安装文件用的http://bbs.eetop.cn/thread-355374-1-1.html，patch将就用的IUS 9.2http://bbs.eetop.cn/thread-268069-1-1.html）

4）calibre 2013.3_39.24

一、virtuoso layout XL无法加载QRC UI
按网上说明，在cdsinit文件加入配置，但layout工具栏上仍然看不到QRC的调用按钮。
二、使用命令运行QRC，生成capfile时报错
报错信息

WARNING (LBMISC-215001): file 'via1' is not a flat edge file

ERROR (LBMISC-215002):
it is a hierarchical edge file

做LVS时已选择Flatten

QRC命令行流程：

1. run lvs by GUI with lvs.cmd (fab provided), and make a clean result

2. run lvs by GUI with xrc.cmd (edited from lvs.cmd according to fab‘s guidance).

3. run calibre：calibre -query_input query_cmd -query svdb xrc_test

4. run：qrc -cmd qrc_cmd
