Error when running XSTREME

[Maoting Chen]

Hi,

I am running xstreme command using MEME suite on docker. 

I ran the following command:

xstreme --oc ./path --time 240  --meme-searchsize 100000 --dna --evt 0.05 --minw 6 --maxw 15 --align right --meme-mod zoops --sea-noseqs --m /opt/meme/share/meme-5.5.9/db/motif_databases/CIS-BP_2.00/Caenorhabditis_elegans.meme --p foreground.fa -n background.fa

The MEME, STREME and SEA analysis ran successfully but then it gave me the error: Can't use an undefined value as an ARRAY reference at /opt/meme/bin/xstreme line 1291.

I have successfully ran another xstreme command with only differences in input .fa files, --align center and different motif_database. 

Could you please help me with how to fix the error?

Thank you,

Maoting
