我有20 df（名为sample1 ... sample20），每个df都使用
加载sample1 = pd.read_table('pathtosample1.csv', sep='\t', index_col=0)["score"]
我再次使用不同的变量为每个文件加载以下元步骤
meta1 = pd.read_table('pathtosample1.csv', sep='\t', index_col=0).loc[:,['junction_id','splice_site','intron_size', 'anchor','genes','transcripts', 'exons_skipped']]
sample1 df
Unique junction_id score splice_site anchor intron_size exons_skipped genes transcripts

表示我使用这些命令仅指示6个样本
concat = pd.concat([sample1,sample2,sample3,sample4,sample5,sample6], axis=1).fillna(0)
concat.columns = ["score_1", "score_2", "score_3","score_4", "score_5", "score_6"]
meta = pd.concat([meta1,meta2,meta3,meta4,meta5,meta6], ignore_index=True)
meta = meta[~meta.index.duplicated(keep='first')]
concat = pd.concat([concat, meta], axis=1)
concat.to_csv('data.csv')
我得到的错误是，
ValueError：无法从重复轴重新索引
我的预期输出是从第一列获取所有文件的第一列中的所有元素，并在列中添加每个样本的分数，然后添加对应于每行的其余元列，预期输出
Junction_id score1 score2 score3 score4 score5 score6 Unique splice_site intron_size anchor genes transcripts exons_skipped
