作用：用两条独立路线填补草图中的剩余 gap：TGS-GapCloser2 用 ONT UL reads，quarTeT GapFiller 用 contig 集作填充序列。
入口：gapcloser.sh 与 quarTeT.sh（互不调用，各自独立提交）
输入：chr2.fa（本地草图，两脚本共用）；ONT UL reads {PROJ_LOTUS_ZC}`/data/Gifu/ont/Gifu-jing-ye.pass.ul.fa`；填充序列 {PROJ_LOTUS_ZC}/Gifu_hifionly/04.tel_check/contigs.fa。
输出：TGS-GapCloser2 的 ont_fill_out.*（填充结果与日志）；quarTeT 的 Gifu_gapfill*（填充后的基因组与绘图文件）。
运行：bash gapcloser.sh；bash quarTeT.sh
工具：TGS-GapCloser2 --scaff chr2.fa --output ont_fill_out --ne --thread 64；quarTeT（quartet.py GapFiller）-d chr2.fa -g <contigs.fa> -p Gifu_gapfill -f 20000 -i 90 -t 88。
English
**Purpose**: Close the remaining gaps in the draft by two independent routes: TGS-GapCloser2 with ONT UL reads, and quarTeT GapFiller using the contig set as filling sequence.
**Entry point**: `gapcloser.sh` and `quarTeT.sh` (neither invokes the other; each is submitted on its own)
**Inputs**: `chr2.fa` (local draft, shared by both scripts); ONT UL reads ``{PROJ_LOTUS_ZC}`/data/Gifu/ont/Gifu-jing-ye.pass.ul.fa`; filling sequence ``{PROJ_LOTUS_ZC}`/Gifu_hifionly/04.tel_check/contigs.fa`.
**Outputs**: TGS-GapCloser2 `ont_fill_out.*` (filled sequence and logs); quarTeT `Gifu_gapfill*` (the filled genome and drawing files).
**Run**: `bash gapcloser.sh`; `bash quarTeT.sh`
**Tools**: TGS-GapCloser2 `--scaff chr2.fa --output ont_fill_out --ne --thread 64`; quarTeT (`quartet.py GapFiller`) `-d chr2.fa -g -p Gifu_gapfill -f 20000 -i 90 -t 88`.
