I have a cluster fasta file (called file) which looks like:

the file has 4 groups: 1AB2, 2AC6, 7KZL, and 6GH3. the content during the first >1AB2 and the first >2AC6 belongs to the cluster 1AB2. the content during the first >2AC6 and the first >7KZL belongs to the cluster 2AC6.

I want to separate the file into 4 files at the second >XXXX with specific names in this index file (ind.txt):

HG001 1AB2
HG010 2AC6
HG023 7KZL
HG004 6GH3

The result file should look like:
