如何修改fasta文件的头信息并将其与另一个文件的信息合并？

1. 读取fasta文件和另一个文件，存储在两个列表中。

   with open("fasta_file.fasta", "r") as f:
       fasta_data = [line.strip() for line in f.readlines()]
   
   with open("other_file.txt", "r") as f:
       other_data = [line.strip().split("\t") for line in f.readlines()]
   

2. 修改fasta文件的头信息。

   new_fasta_data = []
   for row in fasta_data:
       if row.startswith(">"):
           header = row.split()[0]
           for other_row in other_data:
               if header == other_row[0]:
                   new_header = header + "|" + other_row[1] + "|" + other_row[2]
           new_fasta_data.append(new_header)
       else:
           new_fasta_data.append(row)
   

3. 合并fasta文件和其他文件的信息。

   merged_data = []
   for row in other_data:
       header = ">" + row[0] + "|" + row[1] + "|" + row[2]
       for fasta_row in fasta_data:
           if fasta_row.startswith(header):
               sequence = fasta_data[fasta_data.index(fasta_row) + 1]
               merged_row = [row[0], row[1], row[2], sequence]
               merged_data.append(merged_row)
   

完整代码示例：

with open("fasta_file.fasta", "r") as f:
    fasta_data = [line.strip() for line in f.readlines()]

with open("other_file.txt", "r") as f:
    other_data = [line.strip().split("\t") for line in f.readlines()]

# Modify fasta header
new_fasta_data = []
for row in fasta_data:
    if row.startswith(">"):
        header = row.split()[0]
        for other_row in other_data:
            if header == other_row[0]:
                new_header = header + "|" + other_row[1] + "|" + other_row[2]
        new_fasta_data.append(new_header)
    else:
        new_fasta_data.append(row)

# Merge fasta and other data
merged
