Hi, I have been running velveth and velvetg for mapping on a reference file (Columbus extension) but I am getting the following error:
First I ran velveth, using the following script:
./velveth directory 21 -reference Concatenated.fasta -shortPaired -sam Bowtie2_sorted.sam
And the directory result was:
total 249760
drwxr-xr-x 2 vramirezc ucb 4096 Apr 24 11:26 ./
drwxr-xr-x 122 vramirezc ucb 12288 Apr 24 11:26 ../
-rw-r--r-- 1 vramirezc ucb 1158 Apr 24 11:53 Log
-rw-r--r-- 1 vramirezc ucb 255727679 Apr 24 11:26 Sequences
Later, I ran velvetg using:
./velvetg directory -ins_length 400 -exp_cov 10 -min_contig_lgth 100 -unused_reads yes
And then I just obtained an O file (the error file was empty) saying:
[0.000001] No Roadmap file to build upon! Please run velveth (see manual)
[0.000000] No Roadmap file to build upon! Please run velveth (see manual)
[0.000000] No Roadmap file to build upon! Please run velveth (see manual)
[0.000000] No Roadmap file to build upon! Please run velveth (see manual)
Clearly there is no roadmap in the directory file, but I do not know why. Could you please help me?
