Problem in importing tabular blastp output file

I obtained rma files from tabular blastp output files so far, but now it doesn’t work.
I wonder if that’s related to updating megan to current version(V6.6.0). But I uninstalled the previous version and I can’t confirm that.

I specify the blast output format by “-outfmt “6 std staxids stitle qcovs””.
And the output is as follows.

hi_all_scaffold8_1_gene8 gi|763169092|ref|WP_044048745.1| 99.33 297 2
0 1 297 6 302 0.0 573 666509;1284658 membrane protein [Planktomarina temperata] 100

I imported the blast outputs in megan6, using mapping files in megan6 download page (e.g. prot_acc2tax-Aug2016.abin).
It worked well so far. But now no reads are assigned.
(I don’t know if it has relation, but I found that it says “mode=Classifier” in the bottom of megan window, though I choose blastp in import blast file menu.)

Now I’m trying latest blast(ncbi-blast-2.5.0+), and the output is as follows.
In this case, no reads are assigned, too.

hi_all_scaffold8_1_gene8 WP_044048745 99.327 297 2 0 1 297
6 302 0.0 573 666509;1284658 membrane protein [Planktomarina temperata] 100

If you know why it doesn’t work, please advise me.
I also would like to ask which category should be selected in blast tabular file, and which version of blast is recommended for megan use.

The only tab format that MEGAN can import is -m8, which your format isn’t
I recommend using DIAMOND rather than BLAST for aligning reads against a protein reference database

Thank you for reply!
I’ll try to use DIAMOND.
