Simple Protein Structure Parser

Project description

简化版蛋白质二级结构分类器

使用方法

  • 首先通过pip进行安装:
$ python3 -m pip install restraint-fold --upgrade -i https://pypi.org/simple
  • 然后直接在命令行进行使用:
$ python3 -m fold -h
usage: __main__.py [-h] [-i I] [-o O] [-oh OH] [--simplified SIMPLIFIED] [--addh ADDH]

optional arguments:
  -h, --help            show this help message and exit
  -i I                  Set the input pdb file path.
  -o O                  Set the output txt file path.
  -oh OH                Write the hbonds into txt file.
  --simplified SIMPLIFIED
                        Return the simplified information, default to be 0.
  --addh ADDH           Decide to rebuild hydrogen atoms or not, default to be 0.

示例

  • 执行一个生成完整的alpha和beta序列的命令:
$ python3 -m fold -i examples/pdb/case2-optimized.pdb -o examples/case2-secondary.txt
Analysing alpha:
100%|████████████████████████████████████████████████████████████████████████████████████████████| 154/154 [00:00<00:00, 14563.23it/s]
Analysing beta:
100%|█████████████████████████████████████████████████████████████████████████████████████████████| 746/746 [00:00<00:00, 6425.08it/s]

得到的结果如下所示:

# case2-secondary.txt
alpha:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 31 32 33 34 35 36 37 39 40 41 42 43 44 45 46 78 79 80 81 82 83 84 85 86 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109

$ python3 -m fold -i examples/pdb/case2-optimized.pdb -o examples/case2-secondary.txt --simplified 1
Analysing alpha:

得到的结果如下所示:

# case2-secondary.txt
alpha:
1~25
31~37
39~46
78~86
94~109

beta:
23~28

118~157

提示

如果输入的pdb文件中氢原子有缺失,需要加上--addh 1自动补充氢原子的选项,或者手动通过Xponge或者Hadder等工具进行补氢,然后再对结构进行解析:

$ python3 -m fold -i examples/pdb/case2.pdb -o examples/case2-secondary.txt --simplified 1 --addh 1
1 H-Adding task with 2529 atoms complete in 0.09 seconds.
The new pdb file path is in: /tmp/restraint-fold/92de3be6-12f6-11ee-b491-b07b25070cd2.pdb
