cd-hit-2d excluding from clusters good aligments

[Tiltedkid]

Running this command:
cd-hit-2d -i main_set -i2 transcriptos_alternativos -o comparacion_70 -c 0.70 -M 8000 -T 15 -g 1 -G 0 -aS 0.3 -aL 0.3 -A 0.3

Both -i and -i2 are nucleotide

The following cluster is created:

Cluster 6508
0 1305aa, >NonamEVm004010t1... *
1 1303aa, >NonamEVm004010t2... at 1:1177:129:1305/100.00%

in -i2 exists >NonamEVm004010t4 which has 100% identity with >NonamEVm004010t1 (when aligned with external tool). (Identity 100% cover 92%)
NonamEVm004010t4 is found on non-redundant sequences from db2 output
