Can a locally created database be used instead of NR?

Dear Discussion Board,

Will it be wrong to use a locally created database (protein sequences in fasta) instead of NR from PDB? i named my own database to be nr and formated using formatdb , placed it under the path /home/username/ITLIB/nr/nr. Is it theoretically not correct?

Input-

bif@HP:~/Desktop/I-TASSER4.1/I-TASSERmod$ ./runI-TASSER.pl -pkgdir /home/bif/Desktop/I-TASSER4.1 -libdir /home/bif/Desktop/I-TASSER4.1/ITLIB/nr/nr -seqname seq.fasta -datadir /home/bif/Desktop/I-TASSER4.1/example/seq.fasta -java_home /usr/share/java

Output-
Your setting for running I-TASSER is:
-pkgdir = /home/bif/Desktop/I-TASSER4.1
-libdir = /home/bif/Desktop/I-TASSER4.1/ITLIB/nr/nr
-java_home = /usr/share/java
-seqname = seq.fasta
-datadir = /home/bif/Desktop/I-TASSER4.1/example
-outdir = /home/bif/Desktop/I-TASSER4.1/example
-runstyle = serial

-idcut = 1
-ntemp = 20
-nmodel = 5
-light = false
-hours = 50
-LBS = false
-EC = false
-GO = false
