Strange exception in DiscoSNP++ 2.1.7

Question

[adamjorr]

Hi,

I'm getting this exception when trying to run DiscoSNP++:

EXCEPTION: Pool allocation failed for 98 bytes (bank ids alloc). Current usage I s 2439281938 and capacity is 2439282020
there was a problem with graph construction, command line: /bin/DiscoSNP++-2.1.7-Source/build//ext/gatb-core/bin/dbgh5 -in <my files> -out discoRes_k_31_c_4 -kmer-size 31 -abundance-min 4 -abundance-max 2147483647 -solidity-kind max

It seems to be happening during the "counting kmers" step. Is there some kind configuration I'm missing here?

Hi,

Thanks for reporting this issue and sorry for the trouble.

The next (incoming) release should fix this bug. Waiting for this a quick fix is to add the -max-memory 8000 option during the dbgh5 phase (dbg construction).

The following line from run_discoSnp++.sh

$DISCO_BUILD_PATH/ext/gatb-core/bin/dbgh5 -in `echo $read_sets | tr " " ","` -out $h5prefix -kmer-size $k -abundance-min $c -abundance-max $C -solidity-kind max $option_cores_gatb

becomes

$DISCO_BUILD_PATH/ext/gatb-core/bin/dbgh5 -in `echo $read_sets | tr " " ","` -out $h5prefix -kmer-size $k -abundance-min $c -abundance-max $C -solidity-kind max $option_cores_gatb  -max-memory 8000
